Chemistry problem?!?

a graduated cylinder contained 45.0 cc of water. after a piece of metal was dropped in it, water level rose to 72.0 cc. if the cost/g of the metal is P2.75 and its D=18.6 g/cc, how much will the metal cost?
Answer:
1. calculate the volume of metal: 72-45= 27 cc
2. calculate the mass of metal: (27x 18.6) g
3 calculate the cost of metal: (27x18.6x 2.75) and you get the answer: quite easy no?
