Body surface area is an important piece of medical information because it is a factor in temperature regulation as well as some drug level determinations. The Mosteller formula gives one way of estimating body surface area B in square meters. The formula uses the weight w in kilograms and the height h in centimeters. The relation is 8- V hw 60 In this exercise we consider people who are 170 centimeters tall. (a) Write a formula for B as a function of w. B- (b) Make a graph of B versus w.
