SUMMARY
A person weighing 900 N standing on snowshoes with an area of 2500 cm² exerts a pressure of 3600 Pa on the snow. The pressure is calculated using the formula P=F/A, where F is the force and A is the area. The correct area conversion from cm² to m² is crucial for accurate calculations, resulting in a pressure of 1800 Pa when incorrectly calculated. The confusion arises from unit discrepancies, as the answer key lists pressure in Pascals (Pa), which is 1 N/m².
