Noting that pressure is a force over a area (p=f/a, and the equation for gravitational force is f= m x g (where m is the masses of a person in kilograms and g=9.8m/s^2), what pressure [in n/m^2, which is also called pascal (pa)] would be exerted if a 65 kg person were sitting on a stool with a seat diameter of 12 inches?
