Volume calculation practice for cubes using 1 cm unit cubes.

The task is to find the volume of each shape made from 1 cm³ cubes. Since each cube has a volume of 1 cm³, we just need to count how many cubes are in each shape — that number will be the volume in cm³.

Let’s go one by one:

Top row:

1. First shape: It’s a vertical stack of 3 cubes → 3 cubes = 3 cm³
2. Second shape: Looks like an “L” with 4 cubes (3 in a column, 1 sticking out) → 4 cubes = 4 cm³
3. Third shape: A 2x2 square base with 1 on top? Wait — actually, it’s 2 layers: bottom layer has 4 cubes (2x2), top layer has 1 cube → total 5 cubes = 5 cm³

Wait — let me double-check the third one. The image shows a 2x2 base and one cube on top of one corner → yes, 4 + 1 = 5 → correct.

Middle row:

4. Fourth shape: Two separate columns? No — looks like two cubes side-by-side, then one on top of the left one → that’s 3 cubes → 3 cm³
- Actually, looking again: it’s a 2-cube base, and one cube stacked on the left → still 3 cubes → yes.
5. Fifth shape: A diagonal line of 4 cubes → each connected end-to-end → 4 cubes = 4 cm³
6. Sixth shape: Bottom layer has 3 cubes in a row, middle layer has 2 cubes on top of the first two, top layer has 1 cube on the very front → 3 + 2 + 1 = 6 cubes → 6 cm³

Bottom row:

7. Seventh shape: A flat rectangle — 2 rows of 3 cubes each → 2 × 3 = 6 cubes → 6 cm³
8. Eighth shape: A long straight line of 5 cubes → 5 cubes = 5 cm³
9. Ninth shape: Base has 3 cubes in a row, one cube on top of the middle one → 3 + 1 = 4 cubes → 4 cm³

Let me verify all counts once more for accuracy:

1. Stack of 3 → ✔ 3
2. L-shape: 3 down, 1 right → ✔ 4
3. 2x2 base + 1 on top → ✔ 5
4. 2 side by side, 1 on top of left → ✔ 3
5. Diagonal 4 → ✔ 4
6. Pyramid-like: 3 base, 2 middle, 1 top → ✔ 6
7. 2×3 grid → ✔ 6
8. Straight 5 → ✔ 5
9. 3 base, 1 on center → ✔ 4

All checked. Now write them in order as they appear in the worksheet.

Final Answer:
3 cm³, 4 cm³, 5 cm³, 3 cm³, 4 cm³, 6 cm³, 6 cm³, 5 cm³, 4 cm³
