how do we calculate how much we need and how is it done
I do not know how you will keep it from settling but as to the volume 2 = .166 ft average height is 10' = 5/6 = .833 ft I assume a steady slope so I use average thickness 22.166 x 360.166 x .833 = 6,650.2 cu ft = 246.3 cu yds
To figure how much you need find the volume of the area you are filling, Length x width x height. If you are having a truck deliver it you will need to convert this to cubic yards as there is a minimum for delivery. As for how it is done it depends on if you are pouring a slab or a wall.
people always confuse cement with concrete. The concrete volume has been described already, but the quantity of cement per cubic yard averages 5 to 6 sacks of cements per cubic yard. A sack of cement weighs 94 lbs, so you are looking at 470 to 564 lbs of cement per cubic yard of concrete.
