Use the image to answer the question.
An illustration shows a 3-dimensional line diagram of a truck that appears as two adjoining rectangular prisms placed on two visible wheels. The rectangular prism on the left, representing the cab section of the truck, has a height of 3 inches and a horizontal length of 2 inches. The rectangular prism on the right, or the cargo section, is 6 inches high. The back of the truck is marked as 3 inches deep. The total horizontal length of the two prisms combined is 11 inches.

The total surface area of the truck can be calculated by finding the surface area of the cab and the surface area of the shipping container and adding them together.
Surface area of the cab:
2 * (2 * 3) + 2 * (2 * 3) + 2 * (2 * 3) = 12 + 12 + 12 = 36 sq. in.
Surface area of the shipping container:
2 * (6 * 3) + 2 * (6 * 3) + 2 * (3 * 3) = 36 + 36 + 18 = 90 sq. in.
Total surface area of the truck:
36 + 90 = 126 sq. in.
Therefore, the total surface area of the truck (excluding the wheels) is 126 sq. in.
