Answer 2

This problem asks for the surface area of the box, since the contact paper covers the outside (like wrapping paper). The box is 11 x 8 x 9, its length, width, and heighth respectively. And the formula for the surface area of the box is

SA = 2(lw + wh + hl)

SA = 2(11*8 + 8*9 + 9*11)

SA = 2(88 + 72 + 99)

SA = 2(259)

SA = 508 square inches

We are told the contact paper costs eight cents a square inch.

508 square inches x 8 cents / square inch

= $41.44 (the square inches divide out)

Thus, Erin spent $41.444 on contact paper.
