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