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. What is the buoyant force on the block? 2. Relevant equations Fb=p x V x g. P= density of fluid, density of water = 1000 kg/m^3. V=displacement volume. THIS IS WHERE I NEED HELP. How do I find the displacement volume? I have looked everywhere in my notes and can't come up with it. g= 9.8 m/s^2 3. The attempt at a solution 1000 x V?? x 9.8 Need help finding V! Thanks so much.
