document.write( "There are exactly 8 such small cubes - no one more and no one less.\r\n" );

document.write( "Each of these cubes has exactly three painted faces.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the total area under the question is  (2*2)*8*3 cm^2 = 96 cm^2.\r\n" );
