Answer 1

The surface area of the rectangular prism can be calculated by finding the area of each face and then summing them up.

The rectangular prism has 6 faces: 2 rectangles of dimensions 7x3 inches, 2 rectangles of dimensions 3x5 inches, and 2 rectangles of dimensions 7x5 inches.

The area of each face is:
- 7x3 = 21 square inches
- 3x5 = 15 square inches
- 7x5 = 35 square inches

The total surface area is:
2(21) + 2(15) + 2(35) = 42 + 30 + 70 = 142 square inches

Therefore, the surface area of the rectangular prism is 142 square inches.
