The surface area of a rectangular prism can be calculated by finding the area of each of the individual faces and adding them together.
In this case, the rectangular prism has 6 faces:
- 2 faces that are 9 inches by 4 inches (length x height): 2 x 9 x 4 = 72 square inches
- 2 faces that are 9 inches by 3 inches (length x width): 2 x 9 x 3 = 54 square inches
- 2 faces that are 4 inches by 3 inches (height x width): 2 x 4 x 3 = 24 square inches
Adding all these areas together, we get a total surface area of: 72 + 54 + 24 = 150 square inches
Therefore, the surface area of the rectangular prism is 150 in^2.
