To find the surface area of the suitcase, we need to calculate the area of each of its six sides and then sum them up.
The surface area of the front and back sides: 9.5 inches * 22.5 inches = 213.75 square inches each.
The surface area of the top and bottom sides: 16 inches * 22.5 inches = 360 square inches each.
The surface area of the left and right sides: 9.5 inches * 16 inches = 152 square inches each.
Adding up all the areas:
213.75 square inches + 213.75 square inches + 360 square inches + 360 square inches + 152 square inches + 152 square inches = 1451.5 square inches.
Therefore, the surface area of the carry-on suitcase is 1,451.5 in.2.
