To cube a number all you do is multiply it by itself twice. This works for all numbers. So for example 11 cubed is 11 3 or 11 x 11 x 11 which is Another example could be 3 or x x which is 16,, A cube with side length 3 units, volume 27 units ie 3 x 3 x 3 — we can also see there are 27 cubes.
As part of the multiplication and division topic, the national curriculum for Key Stage 2 states that Year 5 pupils should be taught to:. Cube roots, like square roots, or working with squares and cubes of decimals are not generally tackled by children until secondary school closer to GCSE.
Cube numbers are particularly useful when finding the volume of cubes, which children begin to do in Year 5 pupils should be taught to estimate volume [for example, using 1cm 3 blocks to build cuboids including cubes ].
In Year 6, pupils should be taught to calculate, estimate and compare volume of cubes and cuboids using standard units, including cubic centimetres cm 3 and cubic metres m 3 , and extending to other units [for example, mm 3 and km 3 ]. By Year 6 maths pupils will be taught to use their knowledge of the order of operations to carry out calculations and problem solving questions with cubed numbers, including two-step and multi-step word problems.

Using cubes to calculate volume. What is volume? To calculate the number of blocks the squared number we would simply multiply 4 x 4 or 4 2 , equalling To calculate the number of blocks the cubed number this time we would multiply 4 x 4 x 4 or 4 3 equalling Often children will be given a pattern of numbers, such as lower end cube numbers and may be asked to try to work out the pattern. The cube of a negative number will always be negative, just like the cube of a positive number will always be positive.
