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

- The area of the top and bottom faces (9.5 inches x 16 inches) is 152 square inches each.
- The area of the front and back faces (9.5 inches x 22.5 inches) is 213.75 square inches each.
- The area of the side faces (16 inches x 22.5 inches) is 360 square inches each.

Adding up all the areas gives us:
152 + 152 + 213.75 + 213.75 + 360 + 360 = 1451.5 square inches

Therefore, the surface area of the suitcase is 1,451.5 in.²
