I’m sure this is easy but i'm gonna ask anyway
Arada [10]
No, it's always okay to ask if you don't understand a question.  Anyway, for this problem, we just have to plug in the value for <em>V </em>to solve for <em>P</em> :

P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}

A number to the power of 1/3 is the same as taking a cube root.

P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20

The perimeter of one face of the cube is 20m.
