what is the formula for figuring out yards of concrete. 4027 148 cubic yards of concrete For pouring concrete footings 20 feet long 2 feet wide and 1 foot long you would need 148 yards of concrete. Essentially you are solving for volume and then converting to cubic yards.
Please Enter Length In Inches. The formula for concrete calculations is length x width x depth divided by 27. Fortunately figuring out a projects concrete yardage is usually a simple matter of calculating the volume of the space to be spilled and then adding 5-10 to this number to be conservative.
For concrete the formula for volume is as follows.
For large concrete jobs - four cubic yards or more - the concrete should be delivered by a ready-mix truck. Follow the steps below to calculate the total number of cubic yards required. Go to concrete yardage calculator. For concrete the formula for volume is as follows.
