An open-topped box with square base (as in the figure at the right) is to be built for $48.

If the edge-length of the square base is "**x**", express the **VOLUME** **V** of the box as a function of "**x**" by entering integers below (such as 7, 0, or -4). Hint**:** use the first two sentences to express the height of the box in terms of "**x**".
