If it rained 1 inch thick rain over 1 square mile, how much would the rain water weigh?

document.write( "First we find the volume of a rectangular solid 1 mile by 1 mile by 1 inch.\r\n" );
document.write( "\r\n" );
document.write( "V = lwh = (1 mile)(1 mile)(1 inch)\r\n" );
document.write( "\r\n" );
document.write( "We change each of the (1 mile)s to (5280 feet)\r\n" );
document.write( "We change the (1 inch) to ( feet)\r\n" );
document.write( "\r\n" );
document.write( "V = lwh = (5280 feet)(5280 feet)(feet)\r\n" );
document.write( "\r\n" );
document.write( "V = 2323200 cubic feet of water\r\n" );
document.write( "\r\n" );
document.write( "Now we look in a reference book and find that\r\n" );
document.write( "\r\n" );
document.write( "I cubic foot of water weighs 62.38 pounds\r\n" );
document.write( "\r\n" );
document.write( "So we multiply 2323200 by 62.38 and get 144921216 pounds.\r\n" );
