Suppose a woman floats in freshwater with 3.75 % of her volume above the surface of the water. Part (a)  What is the density, in kilograms per cubic meter, of the woman? This could be measured by placing her in a tank with marks on the side to measure how much water she displaces when floating and when held under water (briefly).   Part (b)  What percent of her volume is above the surface when she floats in seawater, with density 1025 kg/m3?
