The surface area S of a human body in square meters can be approximated by S= radical hm/36, where h is height in meters and m is mass in kilograms. A basketball player with a height of 2.1 meters had a surface area of about 2.8 m^2. What is the player’s mass? Round your answer to the nearest whole number.
