Question

The frame for a shipping crate is to be constructed from 24feet of 2x2 lumber.
If the crate is to have square ends of side x feet, express the outer volume v of the crate as a function of x (disregard the thickness of he lumber).

Well, I know that v=lwh, but I don't know what to do with this.
