What is the surface area of a rectangular prism with a length of 16 inches,a height of 4 inches, and a width of 8 inches
The surface area of a rectangular prism is given by the formula:
SA = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the prism.
Substituting the given values, we have:
SA = 2(16 x 8) + 2(16 x 4) + 2(8 x 4)
SA = 256 + 128 + 64
SA = 448
Therefore, the surface area of the rectangular prism is 448 square inches.
