1. The problem statement, all variables and given/known data A cubic meter of some material has a mass of 8600 kg. The block of material is lowered into a lake by a strong cable until the block is completely submerged. Find buoyant force on the block. 2. Relevant equations Fb= p x V x g. p= density of fluid, density of water is 1 g/cm^3. V= displaced volume g=9.8 m/s 3. The attempt at a solution So far I have Fb= 1g/cm^3 x V x 9.8 m/s. I need to find V or the volume displaced by the cube in water. How do I do this? Any help would be appreciated! Thanks!
