Question 1082910
Calculate the volume of water in cubic feet using the area and depth of rainfall. 
Convert cubic feet to cubic inches. 
Convert to gallons using the conversion factor.
Convert to weight using the density of water.
{{{V=A*d}}}
{{{V=27878400(0.083333)}}}
{{{V=2323199}}}{{{ft^3}}}
{{{V=2323199*12*12*12}}}
{{{V=4014487994}}}{{{in^3}}}
There are 231 cubic inches in a gallon so divide the number of cubic inches by 231 to get the number of gallons.
{{{V=4014487994/231}}}
{{{V=17378735.9}}}{{{gallons}}}
Finally multiply by the weight per gallon to get the total weight of the rainfall,
{{{W=17378735.9*8.34}}}
{{{W=144938657}}}{{{lbs}}}
