\r\n" );
document.write( "\r\n" );
document.write( "To start, you should find the total volume. For it, you should multiply\r\n" );
document.write( "\r\n" );
document.write( "    4 *  * 3000 = 4000 cu ft.   (not 3960, which is your value, by mistake !)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "      So, the total volume of 8 equal parts is 4000 cu ft.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next your step is to find the volume for each of 8 parts.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For it, OBVIOUSLY, you should divide 4000 by 8.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The steps that follow are so obvious that I will not go in further details.\r\n" );
