The cube of 28 is 28x28x28. Since 28x28=784, you need to multiply 784 by 28. The easiest way to do this is to treat 28 as being 30-2 and 30 as being 3x10. Multiply 784 by 3 (result = 2352), add a '0' on the end to give 23520, then subtract 784 twice. Once gives you 22736, and once more gives you 21952.
The final answer is thus 21952.

Cube means multiply by itself three times, so:
28*28*28 = 21952

it's like saying 28 to the 3rd power. then U have to write that smaller "3" raised up a bit, right after the 28.
