Question

The figure below is a net for a right rectangular prism the measurements are:
7 in
12 in
7 in
11 in
7 in
7 in
What is the surface area of the right rectangular prism, in square inches?

Answer 1

To find the surface area of the right rectangular prism, we need to find the area of each of the six faces and then add them together.

Face 1: 7 in x 12 in = 84 sq in
Face 2: 7 in x 11 in = 77 sq in
Face 3: 12 in x 11 in = 132 sq in
Face 4: 7 in x 7 in = 49 sq in
Face 5: 7 in x 7 in = 49 sq in
Face 6: 12 in x 7 in = 84 sq in

Total surface area = 84 + 77 + 132 + 49 + 49 + 84 = 475 sq in

Therefore, the surface area of the right rectangular prism is 475 square inches.
