There is no way to calculate cost for a square foot of concrete (?" w x ?" l). In order to calculate cost you need to first calculate volume which requires a third dimension of height (?" w x ?" l x ?" h). Concrete is usually sold by the cubic yard (36" wide x 36" long x 36" high). Another factor in calculating price of concrete is distance to delivery location.
When you purchase concrete you will pay by volume per cubic yard (commonly called "yard"), since a linear yard is 3 feet there are 27 cubic feet in one cubic yard. According to www.doityourself.com a yard of concrete will cost about $75.00 so a cubic foot will cost you $75/27, which would be about $2.78 per cubic foot. 1 foot of concrete is a very small volume so you will probably be charged for a minimum quantity which will be more that the cost of 1 foot. Keep the difference between line, area and volume in mind. If you need less that 10 cubic feet of concrete I would suggest you get a bag of mix from your local hardware store and follow the directions on the bag. You will need a shovel and a bucket or wheel barrel. (a 5 gallon bucket is a little over half a cubic foot) If you are thinking about mixing the concrete yourself, its a good bet to just go to home depot or lowes and write down the cost of various sizes of concrete bags. Once you have that you can enter it into a concrete cost per cubic yard tool (such as: http://righterscientifics.com/concrete-cost-per-yard.html) and figure out the total cost of your project.
Most bags will make a 1/3 of a cubic foot of concrete.
