To calculate the surface area of the air conditioner, we need to find the area of all six sides (top, bottom, front, back, left side, right side) and add them together.
Top and bottom: 23’’ x 25’’ = 575 in2
Front and back: 23’’ x 17’’ = 391 in2
Left and right sides: 25’’ x 17’’ = 425 in2
Total surface area = 2(575) + 2(391) + 2(425) = 1150 + 782 + 850 = 2782 in2
Therefore, the surface area of the air conditioner is 2782 square inches.
