- 1). Find the volume of the fence post footings that will be used. This can be done by multiplying the footing depth by its length and width (cross sectional area), use the area of a circle (3.14 multiplied by the radius squared) for circular footings.
Example: A common footing that measures 18 inches deep, with a cross sectional area of 144 square inches (12 by 12 inches) has a total volume of 2592 cubic inches. - 2). Convert the volume in Step 1 to cubic feet by dividing by 1728 (amount of inches in a cubic foot).
Example: A footing with a volume of 2592 cubic inches divided by 1728, has a total volume of 1.5 cubic feet. - 3). Multiply the volume found in Step 2 by the total number of fence posts to find the total amount of concrete needed in cubic feet.
Example: A fence with 20 fence posts multiplied by 1.5 cubic feet of concrete per post results in a total of 30 cubic feet of concrete for post footings.
