How can you calculate force?

To calculate force, you can use the relationship defined in physics that connects pressure, force, and area. Pressure is defined as the force applied per unit area. Therefore, if you rearrange the equation for pressure (which is pressure equals force divided by area), you arrive at the formula for calculating force as follows:

Force = Pressure × Area.

This relationship means that if you know the pressure exerted on a surface and the area over which that pressure is applied, you can determine the total force exerted. Thus, multiplying pressure by area provides a correct method to calculate force, which aligns with the choice provided.
