To calculate the surface area of the air conditioner, we need to find the area of each of its six faces: top, bottom, front, back, left side, and right side.
Top and Bottom:
Both the top and bottom faces have dimensions of 23" x 25", so their total area is:
2 * (23 * 25) = 1150 in²
Front and Back:
The front and back faces have dimensions of 23" x 17", so their total area is:
2 * (23 * 17) = 782 in²
Left and Right Side:
The left and right side faces have dimensions of 25" x 17", so their total area is:
2 * (25 * 17) = 850 in²
Total Surface Area:
1150 in² (top and bottom) + 782 in² (front and back) + 850 in² (left and right side) = 2782 in²
Therefore, the surface area of the air conditioner is 2782 square inches.
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
