Question

Which represents a perfect cube?

8 times 8 times 8
8 + 8 + 8
9 times 9 times 9 times 9

Answer 1

Anything to the third power is a perfect cube

x.x.x is a perfect cube but x.y.z is not because they have different lengths.

8 times 8 times 8, because that is the equivalent to 8^3, which is a perfect cube
