Let \"+e+\" = length of it's edge
\n" ); document.write( "\"+e%5E2+\" = surface area of one side
\n" ); document.write( "\"+6%2Ae%5E2+\" = surface area of the cube
\n" ); document.write( "---------------
\n" ); document.write( "\"+54+=+6%2Ae%5E2+\"
\n" ); document.write( "\"+e%5E2+=+9+\"
\n" ); document.write( "\"+e+=+3+\"
\n" ); document.write( "The edge is 3 units long
\n" ); document.write( "
\n" ); document.write( "
\n" );
