Picture a 6 inch x 9 inch rectangular cake that is 2 inches tall. If you cover the cake with frosting excluding (2 points)
the bottom, what is the surface area of the cake that will be covered with frosting?
The surface area of the rectangular cake is:
2(6 x 2) + 2(9 x 2) + 2(6 x 9) = 12 + 36 + 108 = 156 square inches
Since we are excluding the bottom, the surface area that will be covered with frosting is:
156 - 54 = 102 square inches
Therefore, the surface area of the cake that will be covered with frosting is 102 square inches.
