Question

Just explain what happened here in the solution

Answer 1

In question 1 :

Force exerted by the box is 1200 Newton

Area covered by the box is 4m sq. .So we have to calculate the pressure exerted by the box. As we know that pressure is equal to Force / Area . So by putting values we will get the answer. And next to our answer we have to write Pa(Pascal) which is the unit of pressure.
