Answer:
volume of cubiod =lbh
=33×18×8 cm cube
= 4752 cm cube
now cions are made by melting the solid metal cubiod therefore there volume must be equal
Therefore.
volume of circular cions = pie ×r×r×h
= 22/7 ×3×3×0.2 r=d/2 =6/2 thickness = 0.2
=39.6/7
=396/7×10
no of cions =volume of cubiod/volume of cions
=4752×7×10
=332640/
396
=840 cions
hope my answer Will be useful to you
