Answer

Explanation:

Step1: Recall the formula for the surface area of a rectangular prism

The formula for the surface area (S) of a rectangular prism with length (l), width (w), and height (h) is (S = 2(lw+lh + wh)).

Step2: Substitute the given values into the formula

Here, (l = 12) inches, (w = 8) inches, and (h=9) inches. First, calculate (lw): (lw=12\times8 = 96). Then, calculate (lh): (lh = 12\times9=108). Next, calculate (wh): (wh=8\times9 = 72). Now, find (lw+lh+wh): (96 + 108+72=276). Finally, multiply by 2: (S=2\times276 = 552) square inches.

Answer:

D. 552 sq. in.
