document.write( "High water level is   = 80 cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Low  water level is   = 60 cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The change of the water volume is  V = A*(80-60) = 20A cm^3,  where A is the base area, in cm^2.\r\n" );

document.write( "    20A = 62600 cm^3\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the equation, the base area  A =  = 3130 cm^2.     ANSWER\r\n" );

document.write( "\r\n" );
document.write( "To find the new height of the water if extra 1565 cm^3 of water added, add    to 80 cm.  You will get then\r\n" );
document.write( "\r\n" );
document.write( "    the new level = 80 +  = 80 + 0.5 = 80.5 cm.     ANSWER\r\n" );
