Aisha packs her toy bricks into a cube-shaped storage box. Each side of the box measures 9 cm. What is the volume of the box?
- 27 cm³
- 81 cm³
- 243 cm³
- 729 cm³
Need a hint?
A cube has three equal dimensions, so multiply the side length by itself three times.
Worked answer
- Volume of a cube = side length × side length × side length.
- Volume = 9 cm × 9 cm × 9 cm = 729 cm³.
Answer: 729 cm³

Calculation slip
Some pupils multiply 9 by itself only once or twice. The volume of a cube requires three equal factors.
