Problem 4 – 8 points a cube of wood with mass m = 1.0 kg floats 80% submerged in a cylinder filled with water (water density = 1000 kg/m3). the cylinder is open to the atmosphere at the top. use g = 10 m/s2 and take atmospheric pressure to be 100 kpa.
(a) calculate the density of the wood.
(b) calculate the minimum mass of a metal cube which, when placed on top of the wood cube, will make the wood cube float 100% submerged.
