The spread footing behaves like an inverted cantilever with loads applied in the upward direction. As a rule, a spread footing is a quite rigid element therefore, the applied soil stresses are almost linear and in case of a symmetric (with respect to the pedestal) footing, they are orthogonal.

How much cement, sand & aggregate required for M25,M20,M15,M10 & M7.5 concrete - Civil Sir Concrete Ratio, Grade Of Concrete, Concrete Steps, Concrete Cement, Concrete Design, Bag Of Cement, High Strength Concrete, Pvc Pipe Fittings

That's 8 bags of cement, 15 CFT of sand and 30 CFT of aggregate are required for one cubic meter (1m3) of M20 concrete. A typical M20 grade of concrete requires 8 bags of cement, 15 CFT of sand and 30 CFT of aggregate per cubic meter.
