Question

Using the formula developed by Dr's Mosteller, doctors can approximate the Body Surface Area (BSA) of an adult. the formula is written as BSA=√HW/3600 where H is the Height in cm and W is the Weight in kg. If the BSA os a certian adult is 1.85 whose height is 189 cm. About how much does this adult weight?

Answer 1

1.85 = sqrt(  189 * w  / 3600 )

 

3.4225 = 189* w/ 3600

 

w = 3.4225*3600/189 = 65.1904762.... kg

 

which is just under

 145 and 1/2 pounds
