Question 1124492


{{{BSA = sqrt ((wh)/3600) }}}, where {{{w}}} = weight in {{{kg}}} and {{{h}}} = height in {{{cm}}}.

Find the weight of a {{{179}}}-cm male to the nearest {{{kg}}} whose {{{BSA = 2.3}}}.


{{{2.3 = sqrt ((w*179)/3600) }}}

{{{2.3 = sqrt (w*179)/sqrt(3600) }}}

{{{2.3 = sqrt (w*179)/60 }}}

{{{2.3 *60= sqrt (w*179)}}}

{{{138= sqrt (w)*sqrt(179)}}}

{{{ sqrt (w)= 138/sqrt(179)}}}.....square both sides

 {{{(sqrt (w))^2= (138/sqrt(179))^2}}}
 
{{{w= 138^2/(sqrt(179))^2}}}

{{{w= 19044/179}}}

{{{w= 106.391061452514}}} kg


{{{w= 106}}} kg, to the nearest kg
