A full can of soda has a mass of 0.421 kg. It contains 3.57 x 104 m3 of liquid. Assuming that the soda has the same density as water, find the volume of aluminum used to make the can.

physics 
MathMate,
Volume of liquid
=3.57*10^4 m^3
=357 ml
mass of liquid
=357 g
mass of aluminium (can)
=421357
=64 g
density of aluminium = 2.7 g/ml
Volume of aluminium = 64/2.7 cc
= 23.7 cc
