In anesthesiology it is necessary to accurately estimate the body surface area of a patient. One formula for estimating body surface ares (BSA) in square metes of a patient of height H (in centimeters) and weight W (in grams ) is :

BSA=0.0003207H0.3W(0.7285-0.0188logW)

(The 0.3 is an exponent of H; the (0.7285-0.0188logW) is an exponent of W)

Find the BSA if W = 49895.2 grams and H = 162.56 centimeters.
