document.write( "1.  The triangles you are talking about are called the lateral faces in this case.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2.  The height of the triangles is called the \"slant height\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "3. There are 4 lateral faces that are triangles with the base of 2 cm and the height of 4 cm.\r\n" );
document.write( "\r\n" );
document.write( "   The area of each such a triangle is  = 4 .\r\n" );
document.write( "\r\n" );
document.write( "   The area of the four triangles is 4*4 = 16 .\r\n" );
document.write( "   It is the \"lateral surface area\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "4.  We must account for the base area too.\r\n" );
document.write( "    It is 4*4 = 20 .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "5.  In all, the total surface area of the given pyramid is 16 + 20 = 36 .\r\n" );
