The issue with the calculation provided is that the formula for the surface area (SA) of a rectangular prism (box) is not correctly specified. The correct formula for the surface area of a rectangular prism is:
\[ SA = 2(lw + lh + hw) \]
This means that the contents of the parentheses (the terms \(wl\), \(lh\), and \(hw\)) should indeed be multiplied by 2 to account for all faces of the prism.
So, the correct response is:
**The contents of the parentheses must be multiplied by 2.**
\[ SA = 2(lw + lh + hw) \]
This means that the contents of the parentheses (the terms \(wl\), \(lh\), and \(hw\)) should indeed be multiplied by 2 to account for all faces of the prism.
So, the correct response is:
**The contents of the parentheses must be multiplied by 2.**
