To find the surface area of a rectangular prism, you need to calculate the area of each of the individual faces (rectangles) and then add them together.
In this case, the net of the rectangular prism consists of 6 rectangles. Since the net shows all dimensions, we can see that the dimensions of the rectangular prism are as follows:
- Length: 5 units
- Width: 4 units
- Height: 3 units
To find the surface area, we calculate the area of each face:
- Front and back faces (2 rectangles): 5 * 3 = 15 units^2 each * 2 = 30 units^2
- Top and bottom faces (2 rectangles): 5 * 4 = 20 units^2 each * 2 = 40 units^2
- Left and right side faces (2 rectangles): 4 * 3 = 12 units^2 each * 2 = 24 units^2
Adding all these areas together: 30 + 40 + 24 = 94 units^2
Therefore, the surface area of the rectangular prism is 94 units^2.

I apologize for the previous incorrect explanation. Let's recalculate the surface area of the rectangular prism based on the provided net.
Looking at the net, we can determine the dimensions of the rectangular prism are as follows:
- Length (L): 5 units
- Width (W): 3 units
- Height (H): 4 units
To find the surface area, we calculate the area of each face represented by the rectangles in the net.
The net consists of:
- Two rectangles of dimensions 5 x 4 units (Front and back faces) = 5 * 4 * 2 = 40 units^2
- Two rectangles of dimensions 5 x 3 units (Top and bottom faces) = 5 * 3 * 2 = 30 units^2
- Two rectangles of dimensions 4 x 3 units (Side faces) = 4 * 3 * 2 = 24 units^2
Adding all these areas together: 40 (front and back) + 30 (top and bottom) + 24 (side faces) = 94 units^2
Therefore, the correct surface area of the rectangular prism is 94 units^2, which was not provided as an option in the multiple-choice responses.

Therefore, the correct surface area of the rectangular prism is 94 units^2, which was not provided as an option in the multiple-choice responses.
