Cube Numbers: Step-by-Step Example
27 October 2026
Cube numbers are an important part of the 11+ maths curriculum. Children often find them easier to understand with a clear, step-by-step example.
Worked example
Find the value of 3 cubed (3³).
Step 1: 3 × 3 = 9
Step 2: 9 × 3 = 27
The answer is 27.
After seeing this example, your child will recognise how a cube number is calculated by multiplying a number by itself twice more. This builds confidence for similar questions, and there are more practice problems ready for your child to try next.
