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 calculate the surface area of the air conditioner, we need to find the surface area of each of its six sides.
1. Front and back sides: 23'' x 17'' = 391 sq. in. x 2 = 782 sq. in.
2. Top and bottom sides: 25'' x 17'' = 425 sq. in. x 2 = 850 sq. in.
3. Left and right sides: 25'' x 23'' = 575 sq. in. x 2 = 1150 sq. in.
Total surface area = 782 sq. in. + 850 sq. in. + 1150 sq. in. = 2782 sq. in.
Therefore, the surface area of the air conditioner is 2782 square inches.
