Looking at the image, we can see a large cross-shaped pattern made up of smaller squares. Each small square is divided into 9 even smaller cells (3x3 grid). Some of these small cells are shaded gray, and some are white.

The key observation is that this is a symmetrical design — it looks like a snowflake or a decorative cross. The shading pattern repeats in a balanced way across the entire figure.

Let’s break down what we’re being asked to find. Since no specific question is written, but the image is given with a task implied, and based on common problems of this type, the most likely question is:

> How many small shaded (gray) cells are there in total?

So let’s count them carefully.

We’ll go section by section. The figure has:

- A top arm (3x3 blocks)
- A bottom arm (3x3 blocks)
- A left arm (3x3 blocks)
- A right arm (3x3 blocks)
- A center block (3x3 blocks)

But note: the arms overlap with the center. So to avoid double-counting, we should think of the whole as:

Top row: 3 blocks wide × 3 blocks high → but only the top part of the cross
Actually, better to divide the entire figure into 5 main sections:

1. Top vertical bar: 3 blocks wide × 3 blocks tall (but actually, looking closely, the top part is 3 blocks wide and 3 blocks high, same for bottom, left, right, and center)

Wait — let me reorient.

Actually, the entire figure is composed of 13 large blocks (each 3x3 small cells):

- Center block
- 4 blocks above center (top arm: 3 blocks high? No — let's count rows and columns of large blocks.

Looking again:

The figure spans 7 large blocks horizontally and 7 vertically? Not exactly.

Better approach: Count each large block individually.

There are 13 large blocks in total forming the cross:

- Top row: 3 blocks (left, center, right)
- Second row: 3 blocks (left, center, right) — but wait, no, the cross shape means:

Actually, standard cross of this type:

Rows of large blocks:

Row 1 (top): 3 blocks (positions 1,2,3)
Row 2: 3 blocks (positions 1,2,3)
Row 3: 7 blocks? No.

Let me label the large blocks by their position.

Imagine a grid of large blocks. The cross occupies:

- Rows 1 to 7, but only certain columns.

Actually, from the image:

The figure has:

- Top part: 3 rows of 3 large blocks each? No.

I think I’m overcomplicating.

Let me count the large blocks that make up the cross:

From top to bottom:

- Row 1: 3 large blocks (left, middle, right) — but in the image, the top row has 3 large blocks side by side? Actually, looking at the image, the top part is 3 large blocks wide and 3 large blocks high? No.

Wait — let's look at the structure.

The entire figure is symmetric. It has:

- A central 3x3 block of large blocks? No.

Actually, the cross is made of:

- 5 large blocks in the vertical line (top to bottom)
- 5 large blocks in the horizontal line (left to right)
- But they share the center block, so total large blocks = 5 + 5 - 1 = 9? But that doesn't match the image.

Looking at the image again:

The figure has:

- Top arm: 3 large blocks high and 3 large blocks wide? No, the top arm is 3 large blocks wide and 3 large blocks high, but it's connected to the center.

Perhaps it's better to count the number of large blocks that are shaded or not — but the shading is within the small cells.

Another idea: perhaps the question is to find how many small cells are shaded in total.

Each large block is 3x3 = 9 small cells.

Now, let's count how many large blocks are there in the entire figure.

From the image:

- The top part: 3 large blocks across, and 3 large blocks down? Let's see the height.

Actually, the figure is 7 large blocks tall and 7 large blocks wide? No.

Let me describe the layout:

The cross has:

- A vertical stem: 7 large blocks tall, 3 large blocks wide
- A horizontal stem: 3 large blocks tall, 7 large blocks wide
- But they overlap in the center 3x3 area.

So total large blocks = (7*3) + (7*3) - (3*3) = 21 + 21 - 9 = 33 large blocks.

Is that right? Let's verify with the image.

In the image, the top part has 3 large blocks in width and 3 in height for the top arm, then the center, then bottom arm.

Actually, from the image, it's clear that the figure is composed of 13 large blocks:

- Top row: 3 blocks
- Second row: 3 blocks
- Third row: 7 blocks? No.

I think I need to count visually.

Let me divide the figure into parts:

1. Top-left corner: 3x3 large blocks? No.

Perhaps the safest way is to count the number of small shaded cells directly by sections.

Since the figure is symmetric, I can count one quadrant and multiply, but it's not perfectly symmetric due to the shading pattern.

Let's take the top-left 3x3 large blocks area.

But perhaps it's easier to notice that each large block has a specific shading pattern, and many are identical.

Looking at the large blocks, there are different types based on their shading.

For example, some large blocks have all 9 cells shaded, some have 5, etc.

But to save time, let's assume that the problem is to count the total number of shaded small cells.

I will go block by block.

First, identify all large blocks in the figure.

From the image, the figure has:

- 3 large blocks in the top row (left, center, right)
- 3 large blocks in the second row (left, center, right)
- 7 large blocks in the third row? No, the third row has the center and extends left and right.

Actually, the figure is 7 large blocks wide and 7 large blocks tall, but only the cross is filled.

Specifically:

- For rows 1 to 7:
- Row 1: columns 1,2,3 (3 blocks)
- Row 2: columns 1,2,3 (3 blocks)
- Row 3: columns 1,2,3,4,5,6,7 (7 blocks) — but in the image, row 3 has blocks from col 1 to 7? Let's see.

Upon closer inspection of the image, the cross is formed as follows:

- The vertical part: from row 1 to row 7, columns 3,4,5 (3 columns wide)
- The horizontal part: from column 1 to column 7, rows 3,4,5 (3 rows high)
- So the intersection is rows 3-5, columns 3-5.

Therefore, the large blocks present are:

- Vertical stem: rows 1-7, cols 3-5 → 7 rows * 3 cols = 21 blocks
- Horizontal stem: rows 3-5, cols 1-7 → 3 rows * 7 cols = 21 blocks
- But the overlap is rows 3-5, cols 3-5 → 3*3 = 9 blocks
- So total large blocks = 21 + 21 - 9 = 33 blocks.

Yes, that makes sense.

Now, each large block is 3x3 = 9 small cells.

Total small cells in the figure = 33 * 9 = 297.

But we need only the shaded ones.

Now, to count shaded cells, I need to look at each large block and see how many of its 9 small cells are shaded.

Since the figure is symmetric, I can group identical blocks.

Let me define the large blocks by their position.

First, the center block: row 4, col 4 (if we number rows 1-7, cols 1-7).

In the image, the center large block (row 4, col 4) has a specific pattern: it has an 'X' made of dashed lines, and some cells shaded.

Looking at the center large block: it has 4 corner cells shaded, and the center cell is white, and the edge centers are white? Let's describe.

Actually, in the center large block, the shading is: the four corners are shaded, and the center is white, and the mid-sides are white. So 4 shaded cells.

But let's confirm with the image.

Perhaps it's better to list the shading pattern for each type of large block.

From the image, I can see that there are several types of large blocks based on their shading:

Type A: All 9 cells shaded — I don't see any.

Type B: 5 cells shaded — for example, the top-left large block in the top row.

Let's take the top-left large block (row 1, col 1).

In the image, for the top-left large block: the first column is all shaded, the second column has only the middle cell shaded, the third column is all white. So that's 3 + 1 + 0 = 4 shaded cells.

Similarly, the top-center large block (row 1, col 2): first column all white, second column all shaded, third column all white — so 3 shaded cells.

This is taking too long. Perhaps there's a better way.

Another idea: since the figure is symmetric, and the shading is consistent, I can count the number of shaded cells in one large block and multiply, but the blocks are not all the same.

Let's count the shaded cells in the top-left 3x3 area of large blocks.

Top-left 3x3 large blocks: rows 1-3, cols 1-3.

But in the figure, for rows 1-2, only cols 1-3 are present; for row 3, cols 1-7 are present, but for the top-left 3x3, we have:

- Block (1,1): as above, 4 shaded cells (col1:3, col2:1, col3:0)
- Block (1,2): col1:0, col2:3, col3:0 — 3 shaded
- Block (1,3): col1:0, col2:1, col3:3 — 4 shaded? Let's see the image.

In the top row, the three large blocks:

- Left: has left column all shaded, middle column only middle cell shaded, right column all white — so 3+1+0=4
- Center: has left column all white, middle column all shaded, right column all white — 0+3+0=3
- Right: has left column all white, middle column only middle cell shaded, right column all shaded — 0+1+3=4

So for top row, shaded cells: 4 + 3 + 4 = 11

Similarly, for the second row (rows 2, cols 1-3):

- Block (2,1): similar to (1,1)? In the image, block (2,1) has left column all shaded, middle column only middle cell shaded, right column all white — same as (1,1) — 4
- Block (2,2): has left column all white, middle column all shaded, right column all white — 3
- Block (2,3): has left column all white, middle column only middle cell shaded, right column all shaded — 4

So again 4+3+4=11

Now for the third row, cols 1-3:

Block (3,1): this is the left part of the horizontal arm.

In the image, for block (3,1): it has the same pattern as (1,1) — left column all shaded, middle column only middle cell shaded, right column all white — 4

Block (3,2): has left column all white, middle column all shaded, right column all white — 3

Block (3,3): has left column all white, middle column only middle cell shaded, right column all shaded — 4

So again 4+3+4=11

But this is only for cols 1-3 in row 3. For row 3, there are also cols 4-7.

Block (3,4): this is the center of the horizontal arm.

In the image, block (3,4): it has a different pattern. Looking at the image, for the center of the cross, the large blocks have a specific shading.

For block (3,4): it has the four corners shaded, and the center cell white, and the mid-sides white — so 4 shaded cells.

Similarly, block (3,5): same as (3,4)? Let's see.

Actually, in the horizontal arm, for row 3, cols 4-7:

Block (3,4): as above, 4 shaded cells (corners)

Block (3,5): this is the center of the cross, but in row 3, col 5.

In the image, block (3,5) has the same as (3,4)? No, let's think.

Perhaps for the central 3x3 large blocks (rows 3-5, cols 3-5), they have a different pattern.

To save time, I recall that in such problems, often the total number of shaded cells is 108 or something, but let's calculate properly.

Another approach: notice that the shading pattern is such that in each large block, the number of shaded cells is either 4 or 3 or 5, but from above, we have 4 and 3.

Let's list all large blocks and their shaded cell count.

First, the vertical stem: rows 1-7, cols 3-5.

For each row in this stem, the three blocks (col3, col4, col5) have specific patterns.

For row 1, col3: this is the top-right of the top arm.

In the image, for block (1,3): as above, 4 shaded cells (0,1,3 for columns)

Similarly, block (1,4): this is the top-center of the top arm.

In the image, block (1,4): has left column all white, middle column all shaded, right column all white — 3 shaded cells.

Block (1,5): has left column all white, middle column only middle cell shaded, right column all shaded — 4 shaded cells.

So for row 1, cols 3-5: 4 + 3 + 4 = 11

Similarly for row 2, cols 3-5: same as row 1, since the top arm is uniform — 4+3+4=11

For row 3, cols 3-5: this is the top of the center.

Block (3,3): as above, 4 shaded cells (same as (1,3))

Block (3,4): this is the center of the cross. In the image, for block (3,4), it has the four corners shaded, and the center cell white, and the mid-sides white — so 4 shaded cells.

Block (3,5): has left column all white, middle column only middle cell shaded, right column all shaded — 4 shaded cells? Let's see the image.

In the image, for block (3,5), it is symmetric to (3,3), so if (3,3) has 4, then (3,5) should have 4.

But earlier for (1,5) we had 4, which is the same pattern.

So for row 3, cols 3-5: 4 + 4 + 4 = 12? But (3,4) is 4, (3,3) is 4, (3,5) is 4, so 12.

But let's confirm with the image.

Perhaps for the central blocks, the pattern is different.

I think I need to accept that and move on.

For row 4, cols 3-5: this is the middle of the cross.

Block (4,3): in the image, this block has a different pattern. Looking at the image, for block (4,3), it has the left column all shaded, middle column only middle cell shaded, right column all white — same as (1,1) — 4 shaded cells.

Similarly, block (4,4): the very center. In the image, it has the four corners shaded, center white, mid-sides white — 4 shaded cells.

Block (4,5): same as (4,3) — 4 shaded cells.

So for row 4, cols 3-5: 4+4+4=12

For row 5, cols 3-5: same as row 3, since symmetric — 4+4+4=12

For row 6, cols 3-5: same as row 2 — 4+3+4=11

For row 7, cols 3-5: same as row 1 — 4+3+4=11

So for the vertical stem (rows 1-7, cols 3-5):

Row 1: 11
Row 2: 11
Row 3: 12
Row 4: 12
Row 5: 12
Row 6: 11
Row 7: 11
Sum for vertical stem: 11+11+12+12+12+11+11 = let's calculate: 11*4 = 44, 12*3 = 36, total 80

But this is for the vertical stem only, which includes cols 3-5 for all rows.

Now for the horizontal stem: rows 3-5, cols 1-7.

But we have already counted cols 3-5 for rows 3-5 in the vertical stem, so for the horizontal stem, we need to add cols 1-2 and cols 6-7 for rows 3-5.

So for row 3, cols 1-2:

Block (3,1): as before, 4 shaded cells
Block (3,2): 3 shaded cells
Sum: 7

For row 3, cols 6-7:

Block (3,6): this should be symmetric to (3,2) — in the image, block (3,6) has left column all white, middle column only middle cell shaded, right column all shaded — 4 shaded cells? Let's see.

Actually, for block (3,6): it is the right part of the horizontal arm.

In the image, for block (3,6): it has the same pattern as block (3,2) but mirrored. Block (3,2) has col1:0, col2:3, col3:0 — so 3 shaded.

Block (3,6) should have col1:0, col2:1, col3:3 for its own columns, but since it's large block, its local columns.

Block (3,6): in the image, it has left column all white, middle column only middle cell shaded, right column all shaded — so 0+1+3=4 shaded cells.

Similarly, block (3,7): has left column all white, middle column all shaded, right column all white — 3 shaded cells? Let's see.

Block (3,7): in the image, it is the far right, so it should have left column all white, middle column all shaded, right column all white — 3 shaded cells.

But earlier for block (3,1) we have 4, block (3,2) 3, block (3,6) 4, block (3,7) 3.

For row 3, cols 1-2: blocks (3,1) and (3,2) : 4 + 3 = 7

Cols 6-7: blocks (3,6) and (3,7) : 4 + 3 = 7

So for row 3, additional shaded cells from horizontal stem: 7 + 7 = 14

But this is for row 3 only.

Similarly for row 4, cols 1-2:

Block (4,1): in the image, this is the left part of the center. It has the same pattern as (3,1) — 4 shaded cells

Block (4,2): same as (3,2) — 3 shaded cells
Sum: 7

Cols 6-7:
Block (4,6): same as (3,6) — 4 shaded cells
Block (4,7): same as (3,7) — 3 shaded cells
Sum: 7

So for row 4, additional: 7 + 7 = 14

For row 5, same as row 3 and 4, since symmetric — additional 14

So for the horizontal stem, the additional shaded cells (not in vertical stem) are for rows 3,4,5 and cols 1-2 and 6-7: 14 + 14 + 14 = 42

Now, total shaded cells = shaded in vertical stem + shaded in horizontal stem additional = 80 + 42 = 122

But is that correct? Let's verify with a different method.

Total large blocks: 33, as before.

Now, let's count how many large blocks have how many shaded cells.

From the image, the large blocks can be categorized as:

- Type 1: 4 shaded cells — for example, the corner blocks of the arms.
- Type 2: 3 shaded cells — for example, the center of the arms.
- Type 3: 4 shaded cells for the central blocks.

In the vertical stem, for rows 1,2,6,7: each has two blocks with 4 shaded cells and one with 3, so per row: 4+3+4=11, and there are 4 such rows (1,2,6,7), so 4*11=44

For rows 3,4,5: each has three blocks with 4 shaded cells, so 3*12=36? 4+4+4=12 per row, 3 rows, 36

So vertical stem: 44 + 36 = 80, as before.

For the horizontal stem additional: for rows 3,4,5, cols 1-2 and 6-7.

For each of these positions, the blocks are:

- For col 1 and col 7: in rows 3,4,5, the blocks have 4 shaded cells each (since they are like the end blocks)
- For col 2 and col 6: in rows 3,4,5, the blocks have 3 shaded cells each

So for row 3: cols 1,2,6,7: blocks with 4,3,4,3 = 4+3+4+3=14
Similarly for row 4: 14
Row 5: 14
Total 42

So overall 80 + 42 = 122

But let's double-check with the center.

Another way: the entire figure has 33 large blocks.

Let's count how many of each type.

From the image, the blocks with 3 shaded cells are:

- In the top arm: for each of rows 1,2, the center block of the three (col4) has 3 shaded cells. So for rows 1,2: 2 blocks with 3 shaded cells.
- Similarly for bottom arm: rows 6,7: 2 blocks with 3 shaded cells.
- In the horizontal arm, for rows 3,4,5, the blocks at col2 and col6 have 3 shaded cells each. So for each row, 2 blocks, 3 rows, so 6 blocks with 3 shaded cells.
- Also, in the vertical stem, for rows 1,2,6,7, the center block (col4) has 3 shaded cells, which we already counted in the top and bottom arms.

So total blocks with 3 shaded cells:
- Top arm: rows 1,2, col4: 2 blocks
- Bottom arm: rows 6,7, col4: 2 blocks
- Horizontal arm: rows 3,4,5, col2 and col6: 3 rows * 2 = 6 blocks
Total: 2+2+6=10 blocks with 3 shaded cells.

Now, the remaining blocks have 4 shaded cells.

Total large blocks: 33
So 33 - 10 = 23 blocks with 4 shaded cells.

Then total shaded cells = 10*3 + 23*4 = 30 + 92 = 122

Yes, same as before.

So the total number of shaded small cells is 122.

Therefore, the answer is 122.

Final Answer: 122
