Volume is length * width * height (depth).


\n" ); document.write( "In this case l = 4 ft., w = 1ft, h=21 inches. Convert inches to feet (divide by 12). So h = 21/12 = 1.75 ft.


\n" ); document.write( "Volume - 4*1*1.75= 7 cubic feet.


\n" ); document.write( "There are appox. 7.48 gallons for each cubic foot. So multiply:


\n" ); document.write( "7*7.48=52.36 gallons.
