Let’s solve each volume problem step by step.
We use the formula:
Volume = length × width × height
All answers must be in
simplified fraction or mixed number form.

Problem 1 (Top Left)
Dimensions:
Length = 5 ft, Width = 3/4 ft, Height = 2 ft
Multiply:
5 × 3/4 × 2
First, multiply 5 × 2 = 10
Then, 10 × 3/4 = 30/4
Simplify 30/4 → divide numerator and denominator by 2 →
15/2
Convert to mixed number: 15 ÷ 2 = 7 with remainder 1 →
7 1/2 ft³
✔ Volume =
7 1/2 ft³
---
Problem 2 (Top Right)
Dimensions:
Length = 1/3 yd, Width = 1/3 yd, Height = 1/3 yd
Multiply:
(1/3) × (1/3) × (1/3) = 1/27
✔ Volume =
1/27 yd³
---
Problem 3 (Middle Left)
Dimensions:
Length = 2 m, Width = 2/5 m, Height = 2 m
Multiply:
2 × 2/5 × 2
First, 2 × 2 = 4
Then, 4 × 2/5 = 8/5
Convert to mixed number: 8 ÷ 5 = 1 with remainder 3 →
1 3/5 m³
✔ Volume =
1 3/5 m³
---
Problem 4 (Middle Right)
Dimensions:
Length = 6 ft, Width = 3/10 ft, Height = 3/10 ft
Multiply:
6 × 3/10 × 3/10
First, 3/10 × 3/10 = 9/100
Then, 6 × 9/100 = 54/100
Simplify: divide numerator and denominator by 2 →
27/50 ft³
✔ Volume =
27/50 ft³
---
Problem 5 (Bottom Left)
Dimensions:
Length = 4 ft, Width = 1/8 ft, Height = 1/8 ft
Multiply:
4 × 1/8 × 1/8
First, 1/8 × 1/8 = 1/64
Then, 4 × 1/64 = 4/64
Simplify: divide numerator and denominator by 4 →
1/16 ft³
✔ Volume =
1/16 ft³
---
Problem 6 (Bottom Right)
Dimensions:
Length = 3 m, Width = 2/15 m, Height = 2/15 m
Multiply:
3 × 2/15 × 2/15
First, 2/15 × 2/15 = 4/225
Then, 3 × 4/225 = 12/225
Simplify: divide numerator and denominator by 3 →
4/75 m³
✔ Volume =
4/75 m³
---
Final Answer:
- Top Left:
7 1/2 ft³
- Top Right:
1/27 yd³
- Middle Left:
1 3/5 m³
- Middle Right:
27/50 ft³
- Bottom Left:
1/16 ft³
- Bottom Right:
4/75 m³
