A carry-on suitcase is 9.5 inches long, 16 inches wide, and 22.5 inches high. What is the surface area of the suitcase? (1 point)
725.75 ln.^ 2
1 ,451.5 ln.^ 2
96in .^ 2
O3, 420in .^ 2
To find the surface area of the suitcase, we need to calculate the area of each side and then sum them up.
The suitcase has 6 sides:
1. One side with a length of 9.5 inches and a width of 22.5 inches, so the area is 9.5 * 22.5 = 213.75 square inches.
2. One side with a length of 9.5 inches and a width of 16 inches, so the area is 9.5 * 16 = 152 square inches.
3. One side with a length of 16 inches and a width of 22.5 inches, so the area is 16 * 22.5 = 360 square inches.
4. One side with a length of 9.5 inches and a width of 16 inches, so the area is 9.5 * 16 = 152 square inches.
5. One side with a length of 16 inches and a width of 22.5 inches, so the area is 16 * 22.5 = 360 square inches.
6. One side with a length of 9.5 inches and a width of 22.5 inches, so the area is 9.5 * 22.5 = 213.75 square inches.
The sum of all the side areas is 213.75 + 152 + 360 + 152 + 360 + 213.75 = 1451.5 square inches.
Therefore, the surface area of the suitcase is 1,451.5 in^2.
