Cube surface area = 6l^2 l is length of edge
\n" ); document.write( "6l^2= 72
\n" ); document.write( "l^2=12
\n" ); document.write( "l= sqrt(12)\r
\n" ); document.write( "\n" ); document.write( "Volume = L*W*H
\n" ); document.write( "\"Volume+=+sqrt%2812%29%2Asqrt%2812%29%2Asqrt%2812%29\"
\n" ); document.write( "\"volume+=+144sqrt%2812%29\"
\n" ); document.write( "V= 499 cu.cm
\n" ); document.write( "
\n" );
