Answer:

$S = 392\ in^2$

Explanation:

Step 1: Determine important information

Using the given numbers it doesn't really matter which is which because the equation multiplies everything together.

Surface Area of a Rectangular Prism →
S= 2(wl+hl+hw)

Step 2: Plug in the values and solve

$S = 2((12\ in * 8\ in) + (5\ in * 8\ in) + (5\ in * 12\ in))$

$S=2(96\ in^2 + 40\ in^2 + 60\ in^2)$

$S = 2(196\ in^2)$

$S = 392\ in^2$

Answer:
$S = 392\ in^2$
