To find the total surface area of the truck, we need to find the surface area of each individual rectangular shape and then add them together.
The cab of the truck has dimensions 6 in. x 2 in. x 3 in. The total surface area of the cab is:
2(6x2) + 2(6x3) + 2(2x3) = 24 + 36 + 12 = 72 in.²
The shipping container has dimensions 3 in. x 3 in. x 11 in. The total surface area of the shipping container is:
2(3x3) + 2(3x11) + 2(3x11) = 18 + 66 + 66 = 150 in.²
Adding the surface area of the cab and the shipping container together:
72 in.² + 150 in.² = 222 in.²
Therefore, the total surface area of the truck (excluding the wheels) is 222 in.². The correct answer is: 222 in.².
6 in.
2 in.
3 in.
3 in.
11 in.
