How many square inches are in a box with width of 5 length of 3 and height of 2?

Multiply 5 x 3 x2=30 inches. I don't agree, 5inX3inX2in=30 CUBIC inches and is the volume of the box. Square inches is a measure of area and the question is meaningless unless you are asking for the surface area of the box or a side of the box.
