Answer:
We are given that a boy is standing on both feet on the floor. The weight of the boy is 40kg and the area of contact of each shoe is 6 cm by 25 cm . Therefore the pressure exerted by the boy is 13.33kNm2or 13.33kPa.

Hint: In the given condition we are given details about a boy who simply stands on the floor. We can say that only the gravitational force acts on the boy as he is standing idle. No other force comes into place at that time. Hence, pressure can be evaluated from gravitational force.
