Step-by-step solution for: Rock bottom Price, Top quality Cube Length Worksheet / Worksheet ...
Let’s solve this step by step.
We are counting cubes to find the volume of each shape. Each small cube = 1 cubic unit. We’ll count how many cubes are in each shape, one at a time.
---
a. Already done: 72 cubic units (example)
---
b. Let’s look at shape b. It’s flat — only 1 layer high.
Count the cubes:
It looks like 3 rows and 5 columns → 3 × 5 = 15 cubes
✔ Volume = 15 cubic units
---
c. Shape c is taller. Let’s break it into parts.
Left part: 3 wide × 4 tall × 2 deep? Wait — let’s count carefully.
Actually, better to count layer by layer or section by section.
Looking at it:
- Bottom layer: 4 across × 3 deep = 12
- Second layer: same as bottom? No — top has less.
Wait — actually, from the drawing:
It’s 3 blocks wide, 4 blocks tall on left side, but right side is shorter.
Better way: Count all visible cubes.
From front view:
Left column: 4 cubes high
Middle column: 4 cubes high
Right column: 2 cubes high
But depth? Looks like 2 layers deep.
So:
Front row: left=4, middle=4, right=2 → total front = 10
Back row: same? Yes, because it’s solid looking.
So back row also: 4 + 4 + 2 = 10
Total = 10 + 10 = 20
Wait — let me double-check.
Actually, looking again — maybe it’s 3 columns wide, 2 deep, and heights vary.
Column 1 (left): 4 high × 2 deep = 8
Column 2 (middle): 4 high × 2 deep = 8
Column 3 (right): 2 high × 2 deep = 4
Total = 8 + 8 + 4 = 20
✔ Volume = 20 cubic units
---
d. Tall thin tower.
Looks like 1 cube wide, 1 cube deep, 6 cubes tall.
So 1 × 1 × 6 = 6
✔ Volume = 6 cubic units
---
e. Blocky shape.
Looks like 3 wide, 2 deep, 3 high? But not full.
Let’s count:
Bottom layer: 3 × 2 = 6
Middle layer: 3 × 2 = 6
Top layer: only 2 cubes? Wait — no, looks like full 3×2 on top too?
Wait — actually, from image: it seems like a rectangular prism: 3 long, 2 wide, 3 high → 3×2×3 = 18
Yes — appears solid.
✔ Volume = 18 cubic units
---
f. Two towers connected? Or L-shape?
Looks like two separate columns? No — connected at base.
Actually, it’s like a U-shape or two pillars with a base.
Wait — better: count each vertical stack.
Left column: 4 high
Right column: 4 high
Base between them: 1 layer, 2 cubes wide? Actually, looks like base is 3 cubes wide (including under both columns), 1 deep.
Wait — perhaps:
Total height 4, width 3, depth 1? But missing middle top?
No — actually, it’s 3 cubes wide, 1 deep, and 4 high — but the middle cube is missing from top 3 layers? That would be complicated.
Wait — looking again: it seems like two separate towers of 4 cubes each, and they’re connected at the bottom by 1 cube? So total = 4 + 4 + 1 = 9? But that doesn’t match visual.
Alternative: think of it as a rectangle minus missing part.
Easier: count every cube you can see and assume hidden ones are there if it’s solid.
Actually, standard interpretation for these worksheets: if it looks solid, it is.
This shape: 3 cubes wide, 1 cube deep, 4 cubes high — BUT the center cube of the top 3 layers is missing? No — looking at image, it seems like it’s two columns of 4, and a bridge at bottom.
Wait — I think it’s:
- Left pillar: 4 cubes
- Right pillar: 4 cubes
- Base connecting them: 1 cube in front? Or behind?
Actually, from perspective, it might be 3 cubes wide, 2 deep? Too confusing.
Let me try another approach.
In many such problems, shape f is often 3x1x4 minus nothing — but here it looks indented.
Wait — perhaps it’s 3 cubes wide, 1 deep, and 4 high, but the middle cube is only present in bottom layer.
So:
Layer 1 (bottom): 3 cubes
Layers 2,3,4: only left and right → 2 cubes each → 2×3 = 6
Total = 3 + 6 = 9
Yes, that matches common patterns.
✔ Volume = 9 cubic units
---
g. Large block with a bite taken out.
Overall: 5 wide, 3 deep, 4 high? But missing some.
Let’s calculate full box first: 5 × 3 × 4 = 60
Now subtract missing part.
Missing part: looks like a 2x2x2 cube missing from corner? From image, it seems like top-right-front corner is cut out — 2 cubes wide, 2 deep, 2 high? But not exactly.
Actually, looking: the indentation is 2 cubes wide, 2 cubes deep, and goes down 2 levels? So missing 2×2×2 = 8 cubes.
But wait — is it fully missing? From image, yes — it’s a notch.
So 60 - 8 = 52
But let me verify by counting differently.
Alternatively, count layer by layer.
Bottom layer: full 5×3 = 15
Second layer: full 5×3 = 15
Third layer: missing 2×2 = 4, so 15 - 4 = 11
Fourth layer: same as third? Missing 2×2 = 4, so 11
Total = 15 + 15 + 11 + 11 = 52
✔ Volume = 52 cubic units
---
h. Small flat shape.
Looks like 3 cubes in a row, 1 deep, 1 high → 3
✔ Volume = 3 cubic units
---
i. Weird shape — like a staircase or zigzag.
Let’s count each cube.
From bottom up:
Bottom: 1 cube
Then above it: 1 cube shifted right
Then above that: 1 cube shifted left? Wait — actually, it’s a vertical stack with offsets.
Actually, it’s 4 cubes stacked vertically, but each is offset — but still 4 cubes total? No.
Looking: it has 4 levels.
Level 1 (bottom): 1 cube
Level 2: 1 cube (to the right of below)
Level 3: 1 cube (to the left of below)
Level 4: 1 cube (to the right)
And also, at level 2, there’s an extra cube sticking out? Wait — no.
Actually, from image: it’s like a snake: starts at bottom, goes up, then right, then up, then left, then up — but each segment is one cube.
So total cubes: let's trace:
Start at bottom: cube A
Above A: cube B (same position) — no, wait.
Better: imagine coordinates.
Assume x,y,z.
Set bottom-left-front as (0,0,0)
Cube at (0,0,0)
Then (0,0,1) — above
Then (1,0,1) — right
Then (1,0,2) — above
Then (0,0,2) — left
Then (0,0,3) — above
That’s 6 cubes.
List:
1. (0,0,0)
2. (0,0,1)
3. (1,0,1)
4. (1,0,2)
5. (0,0,2)
6. (0,0,3)
Yes, 6 cubes.
✔ Volume = 6 cubic units
---
j. Big block with a smaller block attached at bottom.
Main part: 3 wide, 3 deep, 4 high? Wait.
Actually, looks like:
Tall part: 3 wide, 2 deep, 4 high → 3×2×4 = 24
Attached at front: 3 wide, 1 deep, 1 high → 3×1×1 = 3
Total = 24 + 3 = 27
Is the attached part overlapping? No — it’s in front, so additional.
✔ Volume = 27 cubic units
---
k. Flat rectangle.
Looks like 4 long, 2 wide, 1 high → 4×2×1 = 8
✔ Volume = 8 cubic units
---
l. U-shape or arch.
Two towers with a gap.
Each tower: 2 wide, 2 deep, 4 high? Wait.
Left tower: 2×2×4 = 16
Right tower: 2×2×4 = 16
But they are connected at bottom? And gap in middle.
Actually, overall width 6, depth 2, height 4, but middle 2 cubes wide missing from top 3 layers?
Better: count.
Full box: 6×2×4 = 48
Missing part: middle 2×2×3 = 12 (since bottom layer is full)
So 48 - 12 = 36
Verify:
Bottom layer: full 6×2 = 12
Layers 2,3,4: each has 6×2 minus 2×2 = 12 - 4 = 8 per layer → 8×3 = 24
Total = 12 + 24 = 36
✔ Volume = 36 cubic units

Better way: Count all visible cubes.
From front view:
Left column: 4 cubes high
Middle column: 4 cubes high
Right column: 2 cubes high
But depth? Looks like 2 layers deep.
So:
Front row: left=4, middle=4, right=2 → total front = 10
Back row: same? Yes, because it’s solid looking.
So back row also: 4 + 4 + 2 = 10
Total = 10 + 10 = 20
Wait — let me double-check.
Actually, looking again — maybe it’s 3 columns wide, 2 deep, and heights vary.
Column 1 (left): 4 high × 2 deep = 8
Column 2 (middle): 4 high × 2 deep = 8
Column 3 (right): 2 high × 2 deep = 4
Total = 8 + 8 + 4 = 20
✔ Volume = 20 cubic units
---
d. Tall thin tower.
Looks like 1 cube wide, 1 cube deep, 6 cubes tall.
So 1 × 1 × 6 = 6
✔ Volume = 6 cubic units
---

Looks like 3 wide, 2 deep, 3 high? But not full.
Let’s count:
Bottom layer: 3 × 2 = 6
Middle layer: 3 × 2 = 6
Top layer: only 2 cubes? Wait — no, looks like full 3×2 on top too?
Wait — actually, from image: it seems like a rectangular prism: 3 long, 2 wide, 3 high → 3×2×3 = 18
Yes — appears solid.

g. Large block with a bite taken out.
Overall: 5 wide, 3 deep, 4 high? But missing some.
Let’s calculate full box first: 5 × 3 × 4 = 60
Now subtract missing part.
Missing part: looks like a 2x2x2 cube missing from corner? From image, it seems like top-right-front corner is cut out — 2 cubes wide, 2 deep, 2 high? But not exactly.
Actually, looking: the indentation is 2 cubes wide, 2 cubes deep, and goes down 2 levels? So missing 2×2×2 = 8 cubes.
But wait — is it fully missing? From image, yes — it’s a notch.

But let me verify by counting differently.
Alternatively, count layer by layer.
Bottom layer: full 5×3 = 15
Second layer: full 5×3 = 15
Third layer: missing 2×2 = 4, so 15 - 4 = 11

Start at bottom: cube A
Above A: cube B (same position) — no, wait.

Then (0,0,1) — above
Then (1,0,1) — right
Then (1,0,2) — above

Is the attached part overlapping? No — it’s in front, so additional.

l. U-shape or arch.
Two towers with a gap.
Each tower: 2 wide, 2 deep, 4 high? Wait.
Left tower: 2×2×4 = 16
Right tower: 2×2×4 = 16
But they are connected at bottom? And gap in middle.
Actually, overall width 6, depth 2, height 4, but middle 2 cubes wide missing from top 3 layers?
Better: count.
Full box: 6×2×4 = 48
Missing part: middle 2×2×3 = 12 (since bottom layer is full)
So 48 - 12 = 36
Verify:
Bottom layer: full 6×2 = 12
Layers 2,3,4: each has 6×2 minus 2×2 = 12 - 4 = 8 per layer → 8×3 = 24
Total = 12 + 24 = 36
