Final answer:
The surface area of the rectangular prism with sides 2, 3, and 7 is found by substituting these values into the surface area formula (2lw + 2lh + 2wh). This calculation gives a surface area of 82 square units.
Step-by-step explanation:
To find the surface area of a rectangular prism, we use the formula for the surface area of a rectangular prism, which is 2lw + 2lh + 2wh, where l is length, w is the width, and h is the height. In this case, the sides are 2, 3, and 7, so we substitute these values into the formula:
- 2 * 2 * 3 = 12
- 2 * 2 * 7 = 28
- 2 * 3 * 7 = 42
Adding these results, we get: 12 + 28 + 42 = 82. So, the surface area of the rectangular prism is 82 square units.
