A piece of wood floats in water. It measures 25 cm x 15 cm x 19 cm, and has a density of 600 kg/m^3. Find the percent of the wood that's underwater, if the density of water is 1000 kg/m^3 Hint: Answer should be between 0 and 100 % Buoyancy problem: draw the wood and the forces on it - namely gravity pulling down and the buoyant force of the water pushing up F = 0 the buoyant force = Fb = density of fluid x g x Volume underwater = density of fluid x g x percent * total volume solve for percent
