cavity

Answer:
2.5cc
Step-by-step explanation:
specific gravity = 10.5
hence, 10.5g silver displaces 1cc water
then, 1g silver displaces 1/10.5 cc water
then, 288.75g silver displaces 288.75/10.5 cc
= 27.5cc water.
but given, water displaced by silver ornament is 30cc
hence hollow cavity is 30-27.5 = 2.5cc
