Answer 1

The surface area of a rectangular prism can be calculated using the formula:

Surface Area = 2lw + 2lh + 2wh

Given:
Length (l) = 16 inches
Height (h) = 4 inches
Width (w) = 8 inches

Plugging these values into the formula:

Surface Area = 2(16)(8) + 2(16)(4) + 2(8)(4)
Surface Area = 256 + 128 + 64
Surface Area = 448 square inches

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