Since the volume of a cube is equal to the length cubed,\(V= x^{3]\). Substitute 125 for V giving you \(125=x^3\). Take the cubed root of 125 to give you \(x=5\). To find the area of a side, you have to take the length and square it. Therefore, \(A= x^{2}\). Substitute 5 for x giving you \(A=5^2\). Evaluate the equation to give you \(A=25\).
