1. The problem statement, all variables and given/known data I have confusion. Suppose i have metal cube placed in empty vessel. I have seal tight the base of cube so that the water or any fluid can't seep below the cube. Now i pour water into the vessel. Will there be bouyancy on the metal cube ?? If i measure the weight of cube, will it be lesser than its actual weight ? 2. Relevant equations 3. The attempt at a solution I know that bouyancy force is equal to weight of the displaced fluid. The cube will displace the fluid. But since its base is seal tight, there will be no fluid under the base. So there is no fluid under the cube to exert the bouyancy force .
