Answer 1

The surface area of a rectangular prism is calculated by finding the area of each of the six faces and adding them together.

In this case, the formula is:

2lw + 2lh + 2wh

Plugging in the given values:

2(12)(5) + 2(12)(3) + 2(5)(3)
= 120 + 72 + 30
= 222 square inches

Therefore, the surface area of the rectangular prism is 222 square inches.
