Cubes and Cuboids: Calculate Volumes

In this worksheet, students must calculate the volume of the given cubes and cuboids.

'Cubes and Cuboids: Calculate Volumes' worksheet

Key stage:  KS 2

Curriculum topic:   Maths and Numerical Reasoning

Curriculum subtopic:   3D Shapes

Difficulty level:  

Worksheet Overview

QUESTION 1 of 10

You should know the following formulae to work out the volumes of these shapes:




You must know:

  • the side length


Remember that the length, the width and the height will all be equal to the side length, because this is a CUBE.


Volume of cube = side length × side length × side length




You must know:

  • the length
  • the width
  • the height


Volume of cuboid = length × width × height



Example 1

Calculate the volume of this cuboid in cm3.



The length is 15 cm, the width is 4 cm and the height is 8 cm.

Volume of cuboid = length × width × height = 15 × 4 × 8 = 60 × 8 = 480 cm3



Example 2

Calculate the volume of this cube in mm3.



The side length is 7 cm, so the width and the height are also 7 cm.

This will be 70 mm.

NB: We want the answer in mm3 which is why we should work in mm not cm.


Volume of cube = side length × side length × side length = 70 × 70 × 70 = 49 × 7 × 10 × 10 × 10 = 343 × 1000 = 343000 mm3


NB: The length, the width and the height are all interchangeable with each other, depending on how you look at a cuboid.
