Keira is wrapping up her air conditioner for the winter. She needs to determine how much shrink wrap will cover the air conditioner completely. If the dimensions of the air conditioner are 23” x 25” x 17”, what is its surface area in square inches? Use a net to help you calculate your answer. (1 point)
To find the surface area of the air conditioner, we need to calculate the area of each of its six faces.
Face 1: 23" x 25" = 575 square inches
Face 2: 23" x 25" = 575 square inches
Face 3: 23" x 17" = 391 square inches
Face 4: 23" x 17" = 391 square inches
Face 5: 25" x 17" = 425 square inches
Face 6: 25" x 17" = 425 square inches
Total surface area = 575 + 575 + 391 + 391 + 425 + 425 = 2782 square inches
Therefore, Keira will need 2782 square inches of shrink wrap to cover the air conditioner completely for the winter.
