Number of plants required to set an acre of ground at given distances

This table is computed by dividing 43,560 (the number of square feet in an acre) by the product of the two distances, in feet: 43,560 / 6 (2 ft. X 3 ft.) = 7260. This assumes that the acre is full to the margin. A square acre is a little less than 209 ft. on all sides.
