Your volume of aluminum is much larger, 16.7 cc to 2.35 ccYou have your values ma 45g da 2.7g/cc mb 20g db 8.5g/cc You just take how much you have, and invert the density (mass / volume becomes volume / mass) and multiply, the units of mass cancel out, leaving volume: Aluminum (45g) (1cc / 2.7g) 16.7 cc Brass (20g) (1cc / 8.5g) 2.35 cc
