Pressure is defined as the amount of force exerted per unit area. To calculate pressure, the correct formula is derived from the relationship between these three variables. Specifically, it is determined by taking the total force applied and dividing it by the area over which that force is distributed.

This relationship highlights the concept that if a large force is applied over a small area, the pressure will be high, whereas the same force applied over a larger area will result in lower pressure. This principle is essential in various real-world applications, such as understanding how objects behave under different loads, designing equipment that can withstand forces, and analyzing how fluids behave under pressure.
