Question

A silver ornament is suspected to be hollow.Its weight is 288.75 and it can displace 30 cc of water. If the specific gravity of silver is 1.5, then find the volume of the cavity

Answer 1

weight=288.75g

volume displaced=weight of floating object=30g

therefore weight of hollow cavity=288.75g-30g

                                                          =258.75g

density=1.5g/cm3

p=m/v

p*v=m

v=m/p

v=258.75/1.5

v=172.5
