According to Archimedes' principle, the mass of a floating object equals the mass of the fluid displaced by the object. Use this principle to solve the following problems. a. A wooden cylinder 25.0cm in length floats vertically in a tub of water (density =1.00g2/cm3 ). The top of the cylinder is 11.5cm above the surface of the water. What is the density of the wood? g/cm3 b. The same cylinder floats vertically in a liquid of unknown density. The top of the cylinder is 11.9cm above the surface of the liquid. What is the density of the liquid? g/cm3
