\n" ); document.write( "let the length of one side be \"L\"\r
\n" ); document.write( "\n" ); document.write( "given \"A=240cm%5E2\"\r
\n" ); document.write( "\n" ); document.write( "surface area of a cube is \"A=6L%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"240cm%5E2=6L%5E2\"...solve for \"L\"\r
\n" ); document.write( "\n" ); document.write( "\"240cm%5E2%2F6=L%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"40cm%5E2=L%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"sqrt%2840cm%5E2%29=L\"\r
\n" ); document.write( "\n" ); document.write( "\"6.325cm=L\"
\n" ); document.write( "
