L is length;\r
\n" ); document.write( "\n" ); document.write( "If 0.2 cm \"thickness\" means \"diameter, then volume is \"pi%2A%280.2%2F2%29%5E2%2AL\"
\n" ); document.write( "or \"pi%2AL%2A0.1%5E2=pi%2AL%2A0.01=highlight_green%280.01L%2Api%29\" cubic centimeters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now you need to use the density for copper. You find that yourself and use it. You are given, 1 kilogram of copper.\r
\n" ); document.write( "\n" ); document.write( "--\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If your reference source tells 8.96 grams per cubic centimeter is density for copper then you have what you need.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You were given 1 kilogram of copper, which is 1000 grams of copper.
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "\"%281000%2Agrams%29%2F%280.01L%2Api%2Acm%5E3%29=8.96%28grams%2Fcm%5E3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1000%2F%280.01%2AL%2Api%29=8.96\"\r
\n" ); document.write( "\n" ); document.write( "SOLVE FOR L.
