Volume of cuboid =33*18*8=33*144=
Volume of 1 coin = 22/7*3*3*0.2
= 22*1.8/7=
Number of coins =7* 33 *144/22*1.8
= 21*72/1.8 = 21*10*4=840coins
Volume of 1 coin = 22/7*3*3*0.2
= 22*1.8/7=
Number of coins =7* 33 *144/22*1.8
= 21*72/1.8 = 21*10*4=840coins

Given, dimensions of cuboid = 33*18*8.
So volume of cuboid=33*18*8=4752
now volume of one cylindrical coin=πr2 h=(22/7)*3*3*0.2
so no. of coins that can be made by that cuboid=4752/(22/7)*3*3*0.2=808.18 coins
So volume of cuboid=33*18*8=4752
now volume of one cylindrical coin=πr2 h=(22/7)*3*3*0.2
so no. of coins that can be made by that cuboid=4752/(22/7)*3*3*0.2=808.18 coins
