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.
First, we need to calculate the surface area of each side of the air conditioner.
The top and bottom each have an area of 23 x 17 = 391 square inches.
The front and back each have an area of 25 x 17 = 425 square inches.
The two sides each have an area of 23 x 25 = 575 square inches.
To get the total surface area, we add up all of these areas:
391 + 391 + 425 + 425 + 575 + 575 = 2778
Therefore, the surface area of the air conditioner is 2778 square inches.
