1. The problem statement, all variables and given/known data Can somebody please tell me exactly what archimedes prnciple is? 2. Relevant equations 3. The attempt at a solution So, I watched this video: . Apparently if we have a cube in a bucket of water then the mass of the whole cube is equal to the mass of the displaced water. So that means if the cube and the water has the same mass (and obviously the have different density) then the volume of the displaced water is equal to the volue of the cube that is under the water. Is it correct?
