18)From the notes: Solve: Application Problem:
A firm must make open top boxes having a volume of 88 cubic inches. The
cardboard available is 10 x 13 inches. Each box is to be made by taking a
sheet, cutting “squares” out of the corners, and then folding the sides up to
make a box. What size square should be cut from each corner of the initial
sheet? Solve by any method involving synthetic division or graphing
