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.

To calculate the volume of dirt needed to fill a circular area, you first need to find the area of the circle (πr^2, where r is the radius). In this case, for a 14-foot circle, the radius is 7 feet. Once you find the area, you can calculate the volume of dirt needed based on the desired depth of filling the circle.
