Question

A pizza box with a square base is to be made from a rectangular sheet of cardboard by cutting six 1-inch squares from the corners and the middle sections and folding up the sides. If the area of the base is to be 144 in squared, what size piece of cardboard should be used?

Answer 1

When you cut out the 6 1x1 squares, you can crease the folds up. On the width, you'll have 12 inches with 2 folds collapsed up . Comparable for the length. You require 12x12 for 144 for the base.
