A piece of wood 305 mm wide, 305 mm high and 3 m long, weighing 6288.46 N/m3, is submerged vertically (the longest side is into the paper) in a body of water, its upper end being flushed with the water surface. What vertical force is required to hold it in position in Newtons? Use g = 9.81m/s2 and specific weight of water 9.81kN/m3. Note: Do not include units in your answers. Do not round off intermediate values and answer in four decimal places.
