  # Understand Volumes of Cubes, Cuboids and Compound Figures

In this worksheet, students will calculate the volume of cubes, cuboids and compound figures. Key stage:  KS 3

Curriculum topic:   Geometry and Measures

Curriculum subtopic:   Use 3D Shape Knowledge to Solve Problems

Difficulty level:   #### Worksheet Overview

Look at the compound figure below.

Think of it as a large cuboid with the dimensions a x b x d with a smaller cuboid of dimensions b x c x b cut out. a = 10 cm

b = 4 cm

c = 2 cm

d = 6 cm

How would you calculate the volume?

= (volume of the large cuboid) - (volume of the small cuboid)

= (10 x 4 x 6) - (4 x 2 x 4)

= 240 - 32

= 208 cm3

Now it's over to you!
