To find the surface area of the suitcase, we need to calculate the area of each side of the suitcase and then add them up.
Area of the front and back sides: length * height = 9.5 in * 22.5 in = 213.75 in²
Area of the top and bottom sides: width * length = 16 in * 9.5 in = 152 in²
Area of the left and right sides: height * width = 22.5 in * 16 in = 360 in²
Now, add up these areas: 213.75 in² + 152 in² + 360 in² = 725.75 in²
Therefore, the surface area of the suitcase is 725.75 in².
