Answer:
Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.
Step-by-step explanation:
we know that
The amount of paper needed to make the wrapper is equal to the surface area of the chocolate bar
The surface area of a rectangular prism (chocolate bar) is equal to
![SA=2B+PH](https://tex.z-dn.net/?f=SA%3D2B%2BPH)
where
B is the area of the base
P is the perimeter of the base
H is the height of he prism
In this problem we have
![L=80\ mm\\W=5\frac{1}{2}\ mm=5.5\ mm\\H=40\ mm](https://tex.z-dn.net/?f=L%3D80%5C%20mm%5C%5CW%3D5%5Cfrac%7B1%7D%7B2%7D%5C%20mm%3D5.5%5C%20mm%5C%5CH%3D40%5C%20mm)
<em>Find the area of the base</em>
![B=LW=(80)(5.5)=440\ mm^2](https://tex.z-dn.net/?f=B%3DLW%3D%2880%29%285.5%29%3D440%5C%20mm%5E2)
<em>Find the perimeter of the base</em>
![P=2(L+W)=2(80+5.5)=171\ mm](https://tex.z-dn.net/?f=P%3D2%28L%2BW%29%3D2%2880%2B5.5%29%3D171%5C%20mm)
<em>Find the surface area</em>
![SA=2(440)+171(40)\\SA=7,720\ mm^2](https://tex.z-dn.net/?f=SA%3D2%28440%29%2B171%2840%29%5C%5CSA%3D7%2C720%5C%20mm%5E2)
