What this covers

Volume of Rectangular Prisms is taught in Grade 5 (age 10 to 11) as a topic to introduce. It sits in the Measurement strand.

Worked example

Find the volume of a cuboid with length 8 cm, width 5 cm, and height 3 cm.

  1. Use the formula Volume = length × width × height
  2. Calculate 8 × 5 = 40
  3. Multiply by height: 40 × 3 = 120

Answer: 120 cm^3

Answer key

  1. 112 cm3Volume = length × width × height; 4 × 4 × 7 = 112 cm3
  2. 56 cm3Volume = length × width × height; 2 × 4 × 7 = 56 cm3
  3. 180 cm3Volume = length × width × height; 5 × 6 × 6 = 180 cm3
  4. 90 cm3Volume = length × width × height; 6 × 5 × 3 = 90 cm3
  5. 30 cm3Volume = length × width × height; 3 × 5 × 2 = 30 cm3
  6. 126 cm3Volume = length × width × height; 7 × 6 × 3 = 126 cm3
