w width
\n" ); document.write( "h height
\n" ); document.write( "L length\r
\n" ); document.write( "\n" ); document.write( "\"system%28w=h%2B4%2CL=h-9%2CwhL=180%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First two equations formulas in terms of h.
\n" ); document.write( "\"system%28w=h%2B4%2CL=h-9%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute into the volume equation:
\n" ); document.write( "\"%28h%2B4%29%2A%28h-9%29h=180\"
\n" ); document.write( "-
\n" ); document.write( "\"%28h%5E2%2B4h-9h-36%29h=180\"
\n" ); document.write( "\"h%5E3-5h%5E2-36h-180=0\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Using graphing software, taking a decimal approximation for the one real root, h=10.235; and then w and L can be evaluated.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Maybe the \"difference\" interpretation was the wrong one, and different results might happen if, \"L=9-h\", but you can try that if you want, and solve to see what you get.
