To calculate the surface area of a rectangular prism, you need to find the area of all the individual sides and then add them together.
In this case, the rectangular prism has 6 sides:
- Top (5 in x 3 in) = 5 in * 3 in = 15 square inches
- Bottom (5 in x 3 in) = 5 in * 3 in = 15 square inches
- Front (2 in x 3 in) = 2 in * 3 in = 6 square inches
- Back (2 in x 3 in) = 2 in * 3 in = 6 square inches
- Left (2 in x 5 in) = 2 in * 5 in = 10 square inches
- Right (2 in x 5 in) = 2 in * 5 in = 10 square inches
Add all these areas together:
15 + 15 + 6 + 6 + 10 + 10 = 62 square inches
Therefore, the surface area of the rectangular prism is 62 square inches.
