Find the area of a box?

The question is ambiguous. I can determine the outside area of a closed box, given its height H, width W and depth D. The top and bottom are equal area, D x W. The front and back are equal area, H x W. The right and left sides are equal, H x D. So, we have 2 x (DW+HW+HD) = total outside area. If all sides are equal, we have 6xL^2, where L is the length of one of the sides.
