Answer:

No

Reasoning:

If something is a perfect cube, it is able to be put under a cube root (
\sqrt[3]{..}) and will result in an integer (a non-decimal number > 0, basically).

So let's calculate
\sqrt[3]{48}, and see if the result is an integer.


\sqrt[3]{48} = 3.634.......

As you can see, the result is not an integer, therefore 48 is not a perfect cube.
