Answer:

  Will’s Wrapping Company needs 9,980 mm^2 of paper to wrap the chocolate bar.

Step-by-step explanation:

The formula for the area of a rectangular prism can be written ...

  A = 2(LW +H(L+W))

  A = 2(90·50 +3.5(90 +50)) = 2(4500 +3.5(140)) = 2(4990)

  A = 9980 . . . square millimeters
