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.
