To find the surface area of the suitcase, you need to calculate the area of each of its six faces and then add them together.
The area of the first face is 9.5 inches long multiplied by 16 inches wide, which equals 152 square inches.
The area of the second face is 9.5 inches long multiplied by 16 inches wide, which again equals 152 square inches.
The area of the third face is 16 inches wide multiplied by 22.5 inches high, which equals 360 square inches.
The area of the fourth face is 16 inches wide multiplied by 22.5 inches high, which also equals 360 square inches.
The area of the fifth face is 9.5 inches long multiplied by 22.5 inches high, which equals 213.75 square inches.
The area of the sixth face is also 9.5 inches long multiplied by 22.5 inches high, which equals 213.75 square inches.
To calculate the total surface area, you add up all of these areas:
152 + 152 + 360 + 360 + 213.75 + 213.75 = 1451.5 square inches.
Therefore, the surface area of the carry-on suitcase is indeed 1,451.5 square inches.
A carry-on suitcase is 9.5 inches long, 16 inches wide, and 22.5 inches high. What is the surface area of the suitcase? the answer is 1,451.5
