Answer 1

The surface area of a rectangular prism is calculated using the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.

Substitute the values:
2(16)(8) + 2(16)(4) + 2(8)(4)
= 256 + 128 + 64
= 448 square inches

Therefore, the surface area of the rectangular prism is 448 square inches.
