Answer :

Volume of parallelepiped, VP = Product of its three dimensions


VP = 16 × 11 × 10


VP = 1760 cm3


Thickness of coin, t = 2mm = 0.2 cm


Diameter of coin = 2 cm


Radius of Coin, r = 1 cm


Volume of one coin, VC = πr2t



VC = 0.6285 cubic cm


Let the number of coins made be ‘n’


VP = n × VC



n = 2800


2800 coins are made.
