That would depend on the density of the bags of topsoil.
It takes 59.84 gallons to fill eight cubic feet.
To determine how many pounds a cubic 3.5 feet container can hold, you need to know the density of the material being filled into the container. Once you have the density of the material in pounds per cubic foot, you can multiply it by 3.5 cubic feet to find out the total weight the container can hold in pounds.
