Cube numbers worksheets
A cube number is what you get by multiplying a number by itself three times. These free printable worksheets ask for the value of n³ for small whole numbers, which is the other half of knowing cube roots.

What's on this sheet
11³ means 11 × 11 × 11 = 1331, and the little 3 says how many times the number appears rather than what to multiply by. Reading it as 11 × 3 is the classic first mistake and it is worth catching immediately, because the same misreading survives all the way into algebra.
Why this sheet works
The name comes from the shape. A cube with edges of 4 holds 4 × 4 × 4 = 64 unit cubes, which is where the word and the operation meet — and it is worth building one out of blocks once, because the picture makes the third multiplication feel necessary rather than arbitrary.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
