1. The problem statement, all variables and given/known data A block of wood with a specific gravity of .6 with a volume of 100 cm^3 is made to just float in H2O by hollowing out some of the wood and replacing it with a substance of specific gravity of 6.5. How many grams of wood were replaced. 2. Relevant equations Not totally sure - possibly Fbuoy=(weightdensity) x (volume) 3. The attempt at a solution .6(100) + .65(100-v)= 1, but i definitely think I took the wrong approach.
