Concrete is generally sold in cubic yards. Since the measurement is currently in cubic feet, you need to convert that to cubic yards. Do this by multiplying the cubic feet by .037037037. 297.92 cubic feet x .037037037 = 11.03407406 cubic yards. Concrete used for this type of footing must be between 2,000 and 5,000 psi in compression.
