Solve the problem. An open box is to be made from a rectangular piece of tin by cutting two inch squares out of the corners and folding up the sides. The volume of the box will be 100 cubic inches. Find the dimensions of the rectangular piece of tin.
More information is needed to come up with a unique set of Length/Width dimensions. The area of the base must be 50 square inches, since the side height of the box is 2 inches.
(L-2)(W-2) = 50
The smallest rectangle that will do the job is a square, with L = W.
