Doctors can approximate the Body Surface Area (BSA) of an adult (in square meters) using the BSA index: $\displaystyle{B}{S}{A}=\sqrt{{\frac{{{H}\cdot{W}}}{{3600}}}}\usepackage{cmbright}\Huge\$ , where H is the height in centimeters and W is the weight in kilograms.

What is the weight (to the nearest kilogram) of an adult who has a BSA of $\displaystyle{1.96}{{m}}^{{2}}\usepackage{cmbright}\Huge\$ and is $\displaystyle{185}{c}{m}\usepackage{cmbright}\Huge\$ tall?
