I'll guess that "X" is meant to be the same as "x". (This is usually

**not** true in math, so please say if I'm wrong!)

What is the formula for the volume V of a rectangular solid (or box, in this case) with width w, length L, and height h? Plug the expressions they gave you into the formula for the variables. Simplify to get the volume of the larger box. Do the same thing for the smaller box, with w = L = h = x. Then create an equation that says "(large volume) is (three times of)(small volume)". Solve the equation for x.

If you get stuck, please write back showing your work for the steps I gave you. Thanks!
