Calculate the volume of a cube in Go
------------------------------------
A cube has equal side lengths. If each side has length "side",
the volume is:
volume = side * side * side
Go does not have a built‑in exponent operator, and using
math.Pow for a simple cube is unnecessary. Multiplication
is clear and efficient.
