Step-by-step explanation:

Given : A chocolate bar measures 30 mm wide, 70 mm long, and four and one over two mm high

To Find :  how much paper will be needed to make the wrapper.

Solution :

Length of chocolate bar = 70 mm

Width of chocolate bar = 30 mm

Height of chocolate bar =

Since chocolate bar in in the shape of cuboid

Total surface area of cuboid : 2(length*width+width*height+height*length)

Thus the wrapper required to wrap chocolate = 2(70*30+30*4.5+4.5*70)

                                                                          = 2100+135+315

                                                                          = 2(2550)

                                                                          = 5100 square mm

Hence  paper will be needed to make the wrapper.
