To calculate the surface area of the suitcase, we need to find the area of each side and then add them up.

The area of the top and bottom surfaces is given by:
Length × Width = 9.5 inches × 16 inches = 152 square inches

The area of the front and back surfaces is given by:
Width × Height = 16 inches × 22.5 inches = 360 square inches

The area of the two side surfaces is given by:
Length × Height = 9.5 inches × 22.5 inches = 213.75 square inches

Now, we can add up these areas to find the surface area of the suitcase:
152 square inches + 360 square inches + 213.75 square inches = 725.75 square inches.

Therefore, the surface area of the carry-on suitcase is 725.75 square inches.
