Answer 1

To find the surface area of the rectangular prism, we can use nets.

First, calculate the area of each face of the rectangular prism:
- Front and back faces: 7 inches x 11 inches = 77 square inches x 2 = 154 square inches
- Top and bottom faces: 7 inches x 3 inches = 21 square inches x 2 = 42 square inches
- Side faces: 3 inches x 11 inches = 33 square inches x 2 = 66 square inches

Now, add up the areas of all the faces:
154 + 42 + 66 = 262 square inches

Therefore, the surface area of the rectangular prism is 262 square inches.

So, the correct response is:
262 in.2
262 in squared
