Question from Sadie: can you help me to find out how to cube a number |
Hi Sadie,
To cube a number you multiply the number by itself (that's the square of the number) and then you multiply the square by the number again. So 6 cubed is 6 × 6 × 6 = 36 × 6 = 216. We often write 6 cubed as 63.
I hope this helps,
Penny
