Represent your unknowns: Let s be the length of one side of the box. The relationship between s and x is s = x-4.
The volume of the box is (length)(width)(height), which here equals the following: V(x) = (x-4)*(x-4)*(x). You may either leave this result as is, or shorten it to V(x) = (x-4)^2*x, or expand (x-4)*(x-4)*(x).
