Why is the bottom part of the foundation of a building made wider?

उत्तर
P ∝ 1/A i.e. pressure is inversely proportional to surface Area
Greater the area, lesser is the pressure.
In order that building should exert less pressure, the foundation of the building should have more area or be wider. So that building should not sink into the earth.
