A 9 in. by 18 in. sheet of cardboard is being made into a box for a class project. Squares with side length x are cut from each corner of the sheet, and then the sides are folded up to form the box. One expression for the volume of the box is (18-2x)(9-2x)x. Interpret the factor 18-2x, in the context of the problem.

• The factor 18-2x represents the height of the box.

• The factor 18-2x represents the length of the box.

• The factor 18-2x represents the width of the box.

• The factor 18-2x represents the volume of the box.
