You can put this solution on YOUR website!
y=kx^(1/2)/w^(1/3)
\n" ); document.write( "find k
\n" ); document.write( "10=k*80^(1/2)/30^(1/3)
\n" ); document.write( "10*30^(1/3)/80^(1/2)=3.474
\n" ); document.write( "Use k in the next part
\n" ); document.write( "y=3.474*sqrt(5)/cube root (3)
\n" ); document.write( "5.386 \n" ); document.write( "

\n" );
