Question

How many solid coins of diameter 6 cm and thickness 0.2 cm can be made by melting a solid metal cuboid of length 33 cm, breath 18 cm and height 8 cm ?

Answer 1

Answer:

840

Step-by-step explanation:

volume of coin = πr²*thicknes

=(22/7)* (6/2)²*0.2

Total Volume of cuboid = 33* 18 * 8

Number of coins = (33*18*8)/((22/7)* (6/2)²*0.2)

= 840
