Answer
pizza box
pizza box  
Suppose you want to make a square-base, open-top box from a square of cardboard by removing a 1-inch square from each corner and folding up the sides.

If the area of the base is 144 in², then each edge of the base is √144 = 12 inches long.
Since the sides will be 1 inch high, the cardboard must be 12+2(1) = 14 inches wide, and 14 inches long.

A pizza box is like two of these open boxes connected, except they share one 12×1 side. The cardboard must be 14 inches wide, and 2(14) - 1 = 27 inches long.
