1. The problem statement, all variables and given/known data A cube of metal(density=6.00 kg/dm^3) has a cavity inside it. It weighs 2.40 times as much in air as it does when completely submerged in water. What fraction of the cube's volume is the cavity? 2. Relevant equations Density=m/v Fb=Density of fluid times volume of fluid times g F=mg 3. The attempt at a solution I first made two equations: Density=m/v (for water) Density=m/v 6.00 kg/dm^3=m/1000 kg 6.00 kg/dm^3/2.40m/V Idk what 2 do from there because I think I set the equations up wrong could someone please explain 2 me what I should do cuz what's really bugging me is the amount of information that is given to me?
