\r\n" );
document.write( "First, we should calculate the volume of water.\r\n" );
document.write( "\r\n" );
document.write( "The volume is the product of the base area (43,560 sq. ft) by the height \r\n" );
document.write( "(= the depth) of water, which is 6.135 ft in this problem.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the volume of water is  43560*6.135 = 267240.6 ft^3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, we should calculate how much gallons is it.\r\n" );
document.write( "From the conversion table, 1 ft^3 = 7.48052 gallons.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, 267240.6 ft^3 of water is equivalent to 267240.6*7.48052 = 1999098.653112 gallons of water.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "One gallon of water weights 8.74 lbs.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So,  1999098.653112 gallons of water weight  1999098.6531120*8.74 = 17472122.2282 lbs.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To convert it to tons, we should divide the number of lbs by 2000.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "S, we do it, and we obtain   = 8736.061 tons of water.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Finally, we round to closest ton, and get the \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  This amount of water is about 8736 tons.\r\n" );

\n" ); document.write( "\n" ); document.write( "This problem is super-simple, and a bit of common sense is enough to solve it to the end.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To better understand this amount of water, imagine a train of 50 cisterns of 20 tons of water in each.\r
\n" ); document.write( "\n" ); document.write( "One such train carries 50*20 = 1000 tons of water. The length of such a train is about one kilometer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, 8736 tons of water is about 9 (nine) such trains.\r
