The correct response is: **The contents of the parentheses must be multiplied by 2.**
The formula SA = (wl + lh + hw) does not correctly represent the surface area of a rectangular prism (or box). The surface area should include twice the sum of the areas of all three pairs of opposing faces. The correct formula for the surface area (SA) is:
\[ SA = 2(wl + lh + hw) \]
This accounts for all the opposite faces of a rectangular prism.
