70 sq feet x 18 inches deep is easiest to calculate if all units are in feet. 18 inches is 1.5 feet deep. Volume is calculated using length x width x depth. Length and width are already factored in so all we need to do is multiply area by depth to get volume. 70 sq. feet x 1.5 feet deep equals 105 cubic feet. If you need measurement in cubic yards (i.e. when having soil delivered on a truck) you need to divide your cubic feet by by 27 cubic feet per yard to arrive at cubic yardage. A yard is 3 feet long so 3 ft. x 3 ft. x 3 ft. equals 27. Therefore 105 cu. ft. / 27 equals 3.9 yards.
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
I think 17 or maybe 38
2.37 cubic yards.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.

if you mean a 30 foot diameter circle, then pi x 152 x 3 = 2119.5 cubic feet of dirt
Depends on how deep you want to fill it...
If the raised garden has dimensions of 5 x 5 x 1 then it requires 25 cubic feet of dirt to fill it.

You will need 1500 cubic feet.
2.37 cubic yards.
