To calculate the surface area of the suitcase, we can use the formula for the surface area of a rectangular prism:
Surface Area = 2(length * width + length * height + width * height)
Substituting the given values:
Surface Area = 2(9.5 * 16 + 9.5 * 22.5 + 16 * 22.5)
Surface Area = 2(152 + 213.75 + 360)
Surface Area = 2(725.75)
Surface Area = 1451.5 square inches
Therefore, the surface area of the carry-on suitcase is 1451.5 square inches.
