Keira is wrapping up her air conditioner for the winter. She needs to determine how much shrink raffle cover of air conditioner completely. The dimensions of the air conditioner are 23×25×17. What is the surface area is square inches? Use a net to help you calculate your answer. Period.
To determine the surface area of the air conditioner, we first need to calculate the surface area of each of the six sides of the rectangular prism.
Front and back sides:
Each of these sides has dimensions 23×25, so their surface area is:
2 × 23 × 25 = 1150 square inches
Top and bottom sides:
Each of these sides has dimensions 23×17, so their surface area is:
2 × 23 × 17 = 782 square inches
Left and right sides:
Each of these sides has dimensions 25×17, so their surface area is:
2 × 25 × 17 = 850 square inches
Total surface area of the air conditioner:
1150 (front and back) + 1150 (front and back) + 782 (top and bottom) + 782 (top and bottom) + 850 (left and right) + 850 (left and right) = 4464 square inches
Therefore, the total surface area of the air conditioner is 4464 square inches.
