Quizplus · Accepted Answer

Pressure is defined as force (or weight in this context) divided by the area over which the force is distributed. The man has the largest area (100 cm^2) for his weight (600 N), resulting in the lowest pressure compared to the child and the woman, who have smaller areas for their respective weights.
