The relative density of an alloy is 6.5.a.find the mass of a solid cube of side 20cm.b.what volume of the alloy has a mass of 13kg

1 answer

cc = cubic centimeter

density = 6.5 grams/cc

volume of cube = 20*20*20 = 8,000 cc
so
mass = 6.5 gms/cc *8, 000 cc = 52,000 gms = 52 Kg

13 kg (8,000cc/52kg) = 2,000 cc
