Answer:

width=7 cm

Step-by-step explanation:

perimeter=2(lengths+width)

   56-42  =2x

        2x    = 14

            x   =7    

therefore the width=7 cm

There are several information's already given in the question. Based on those information's the answer can be deduced.
Mass of the diamond = 4289.6 grams
Density of the diamond = 3.51 gm/cm^3
