Calculate the volume of water in cubic feet using the area and depth of rainfall.
\n" ); document.write( "Convert cubic feet to cubic inches.
\n" ); document.write( "Convert to gallons using the conversion factor.
\n" ); document.write( "Convert to weight using the density of water.
\n" ); document.write( "\"V=A%2Ad\"
\n" ); document.write( "\"V=27878400%280.083333%29\"
\n" ); document.write( "\"V=2323199\"\"ft%5E3\"
\n" ); document.write( "\"V=2323199%2A12%2A12%2A12\"
\n" ); document.write( "\"V=4014487994\"\"in%5E3\"
\n" ); document.write( "There are 231 cubic inches in a gallon so divide the number of cubic inches by 231 to get the number of gallons.
\n" ); document.write( "\"V=4014487994%2F231\"
\n" ); document.write( "\"V=17378735.9\"\"gallons\"
\n" ); document.write( "Finally multiply by the weight per gallon to get the total weight of the rainfall,
\n" ); document.write( "\"W=17378735.9%2A8.34\"
\n" ); document.write( "\"W=144938657\"\"lbs\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
