Question 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 area of each of its six sides and then add them together.
Side 1: 23 x 25 = 575 sq in
Side 2: 23 x 25 = 575 sq in
Side 3: 25 x 17 = 425 sq in
Side 4: 25 x 17 = 425 sq in
Side 5: 23 x 17 = 391 sq in
Side 6: 23 x 17 = 391 sq in
Total surface area = 575 + 575 + 425 + 425 + 391 + 391 = 2782 sq in
Therefore, the surface area of the air conditioner is 2782 square inches.
The net of the air conditioner would show the six sides laid out flat and connected by edges. This would allow you to visualize how the surface area is calculated by breaking it down into individual rectangles.
