.
an elephant of mass 1500 kg stands on its four legs each of area 1.2%2A10%5E%28-2%29 m^2
calculate the pressure exerted by each legs of the elephant on the ground [g = 10m/s^-2]
---------------------------------------------------------------------

The pressure P (in Pascals) is the weight W = M*g  (in newtons)  divided by the area S = 4%2A1.2%2A10%5E%28-2%29 m%5E2:


P = W%2FS = %28M%2Ag%29%2FS = %281500%2A10%29%2F%284%2A1.2%2A10%5E%28-2%29%29 = 15000%2F0.048 = 312500 Pa.


It is slightly more than 3 times the atmospheric pressure (101325 Pa).
