Year 10 Volume of Prisms and Cylinders Worksheet — Level 2 — Practice Set 2 — Answers
Show your working. Volume is measured in cubic units (cm³).
1.A rectangular prism is 13 cm long, 10 cm wide and 2 cm high. Find its volume.
Answer: 260 cm3
- V = length × width × height = 13 × 10 × 2
- = 260 cm3
2.A rectangular prism has a volume of 180 cm3. Its base is 4 cm by 5 cm. Find its height.
Answer: 9 cm
- Base area = 4 × 5 = 20 cm2
- Height = 180 ÷ 20 = 9 cm
3.A rectangular prism is 10 cm long, 6 cm wide and 6 cm high. Find its volume.
Answer: 360 cm3
- V = length × width × height = 10 × 6 × 6
- = 360 cm3
4.A rectangular prism has a volume of 400 cm3. Its base is 10 cm by 5 cm. Find its height.
Answer: 8 cm
- Base area = 10 × 5 = 50 cm2
- Height = 400 ÷ 50 = 8 cm
5.A triangular prism has a triangular end with base 4 cm and height 10 cm. The prism is 9 cm long. Find its volume.
Answer: 180 cm3
- Area of the triangle = ½ × 4 × 10 = 20 cm2
- V = area of end × length = 20 × 9
- = 180 cm3
6.A rectangular prism has a volume of 252 cm3. Its base is 7 cm by 4 cm. Find its height.
Answer: 9 cm
- Base area = 7 × 4 = 28 cm2
- Height = 252 ÷ 28 = 9 cm
7.A triangular prism has a triangular end with base 10 cm and height 10 cm. The prism is 7 cm long. Find its volume.
Answer: 350 cm3
- Area of the triangle = ½ × 10 × 10 = 50 cm2
- V = area of end × length = 50 × 7
- = 350 cm3
8.A triangular prism has a triangular end with base 22 cm and height 7 cm. The prism is 14 cm long. Find its volume.
Answer: 1,078 cm3
- Area of the triangle = ½ × 22 × 7 = 77 cm2
- V = area of end × length = 77 × 14
- = 1,078 cm3
9.A rectangular prism has a volume of 60 cm3. Its base is 10 cm by 3 cm. Find its height.
Answer: 2 cm
- Base area = 10 × 3 = 30 cm2
- Height = 60 ÷ 30 = 2 cm
10.A rectangular prism is 4 cm long, 11 cm wide and 10 cm high. Find its volume.
Answer: 440 cm3
- V = length × width × height = 4 × 11 × 10
- = 440 cm3
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
