How many square inches of cardboard are used? a box has six sides correct 12*6( because the length is 12 and the box has 4 sides which the length is 12) =72(4) for the amount of sides =288 Now do the ends 8*6=48(2) for the two ends of the box 96 288+96=384 inches squares does that match the answer in the book?
