3000 cubic inches of volume is \"2%2F3-1%2F4\" of tank volume.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"20%2A20%2AL=3000\", using L for the length portion that corresponds to the 3000 inch^3 difference. The length along the rectangular tank directly corresponds to volume.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%2F3-1%2F4\"
\n" ); document.write( "\"8%2F12-3%2F12\"
\n" ); document.write( "\"5%2F12\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "L is \"5%2F12\" of the whole length of the rectangular tank.
\n" ); document.write( "\"L=3000%2F%2820%2A20%29\"
\n" ); document.write( "\"L=30%2F4\"
\n" ); document.write( "\"L=15%2F2\", inches.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "With no further explanation,
\n" ); document.write( "\"3000%2812%2F5%29\"
\n" ); document.write( "\"600%2A12\"
\n" ); document.write( "\"highlight%287200%2Ainch%5E3%29\", tank capacity
