5 U.S. gallons of water weigh approximately 41.73 lbs. 5 Imperial gallons of water weigh exactly 50 lbs.
8.2lbs/gallon add together 8.2 times 30= ?
Soil weighs about 2.5 times as much as water, which weighs about 8 pounds per gallon. However, one must estimate the porosity (void space) in the soil. Assuming 30% soil porosity means that one gallon of soil would weigh (0.7 x 2.5 x 8 pounds/gallon) about 14 pounds. Therefore, if full to the brim with soil (relatively dry), the drum would weigh about 770 pounds (that is, 55 gallons x 14 pounds/gallon). In reality, there is a range of possible weights, depending on soil density, moisture content, soil composition, etc.
