As discussed a person’s percentage of body fat can be estimated by weighing the person both in air and underwater, from which the average density ρavgcan be calculated. A widely used equation that relates average body density to fat percentage is the Siri equation, , body fat = (495/ρavg) - 450, where ρavg is measured in g/cm3. One person’s weight in air is 947 N while his weight underwater is 44 N. What is his percentage of body fat?
