Question:

Physicians, particularly pediatricians, sometimes need to know the body surface area of a patient. For instance, they use surface area to adjust the results of certain tests of kidney performance. Tables are available that give the approximate body surface area A in square meters of a person who weighs W kilograms and is H centimeters tall. The following empirical formula is also used: A = .007W 0.425H0.725.

Evaluate

and give a physical interpretation of your answers. You may use the approximations (54)0.425 ≈ 5.4, (54)-0.575 ≈ .10, (165)0.725 ≈ 40.5, and (165)-0.275 ≈ .25.
