Answer: 28 cm3

  1. Area of the triangle = ½ × 4 × 2 = 4 cm2
  2. V = area of end × length = 4 × 7
  3. = 28 cm3
2.A triangular prism has a triangular end with base 12 cm and height 3 cm. The prism is 12 cm long. Find its volume.

Answer: 216 cm3

  1. Area of the triangle = ½ × 12 × 3 = 18 cm2
  2. V = area of end × length = 18 × 12
  3. = 216 cm3
3.A rectangular prism has a volume of 315 cm3. Its base is 7 cm by 5 cm. Find its height.

Answer: 9 cm

  1. Base area = 7 × 5 = 35 cm2
  2. Height = 315 ÷ 35 = 9 cm
4.A triangular prism has a triangular end with base 22 cm and height 3 cm. The prism is 4 cm long. Find its volume.

Answer: 132 cm3

  1. Area of the triangle = ½ × 22 × 3 = 33 cm2

  3. = 132 cm3
5.A triangular prism has a triangular end with base 10 cm and height 6 cm. The prism is 11 cm long. Find its volume.

Answer: 330 cm3

  1. Area of the triangle = ½ × 10 × 6 = 30 cm2
  2. V = area of end × length = 30 × 11
  3. = 330 cm3
6.A rectangular prism has a volume of 180 cm3. Its base is 10 cm by 2 cm. Find its height.

Answer: 9 cm

  1. Base area = 10 × 2 = 20 cm2
  2. Height = 180 ÷ 20 = 9 cm
7.A rectangular prism is 3 cm long, 10 cm wide and 8 cm high. Find its volume.

Answer: 240 cm3

  1. V = length × width × height = 3 × 10 × 8
  2. = 240 cm3
8.A rectangular prism has a volume of 288 cm3. Its base is 8 cm by 6 cm. Find its height.

Answer: 6 cm

  1. Base area = 8 × 6 = 48 cm2
  2. Height = 288 ÷ 48 = 6 cm
