Hint: Volume: Area x length pi X (diameter)? / 4 X L (in cubic feet) then 1 cubic feet you have 1/0.133681 gallons of water. So, volume (in gallons) is: Volume (in cubic feet) X 1/0.133681 then convert gallons to lbs by multiplying with 8.35 Remember that the units should be the same for length. Convert inches to feet first!
