The Mosteller formula for approximating the surface area, S, in m^2, of a human is given by S = ?hw/60, where h is the person's height in cm and w is the person's weight in kg. Complete parts a), b), and c) below.c) The change in S due to a change in w when h is constant is approximately ?S ? (?s/?w)?w. Use this formula to approximate the change in someone's surface area given that the person is 150 cm tall, weights 78 kg, and losses 3kg.The change in surface area is approximately _______ m^2.(Round to four decimal places as needed.)
