Answer 1

To find the surface area of the rectangular prism, we can first calculate the area of each of the six faces.

Face 1: 7 inches x 3 inches = 21 square inches
Face 2: 7 inches x 11 inches = 77 square inches
Face 3: 3 inches x 11 inches = 33 square inches

Now, we can add up the areas of all six faces:
2(21) + 2(77) + 2(33) = 42 + 154 + 66 = 262 square inches

Therefore, the surface area of the rectangular prism is 262 square inches. So the correct answer is:

262 in.2
262 in squared
