Express the volume of a cube as a fuction of the total surface area

2. Relevant equations

Surface area = 6x^2

Volume = x^3

3. The attempt at a solution

So, we need to manipulate the surface area equation so we can use it to find volume right?

SA = 6x^2

sqrt(SA/6) = x

or (SA/6)^(1/2) = x

and sub it in the Volume equation

(SA/6)^(1/2)*3

so we would have (SA/6^3)^3/2

Is this correct answer to the question?
