Use the image to answer the question.

An illustration shows the unfolded version of a rectangular prism composed of 6 rectangles. There are four adjoining rectangles positioned horizontally. The first and third are similar and bigger. The second and fourth are similar and smaller. The first rectangle is labeled 7 inches on the top horizontally. The second rectangle is labeled as 3 inches on the top and 5 inches vertically. The third rectangle shares the top and bottom sides with two similar rectangles, one on each side.

Answer 1

The surface area of the rectangular prism can be calculated by adding the areas of all six rectangles.

1. First rectangle: 7 inches long and 5 inches wide
Area = 7 x 5 = 35 square inches

2. Second rectangle: 3 inches long and 5 inches wide
Area = 3 x 5 = 15 square inches

3. Third rectangle: Similar to the first rectangle, so the area is also 35 square inches

4. Fourth rectangle: Similar to the second rectangle, so the area is also 15 square inches

Adding all the areas together: 35 + 15 + 35 + 15 + 35 + 15 = 150 square inches

Therefore, the surface area of the rectangular prism is 150 square inches.
