How to apply a pressure of 1 kPa with a force of 5 kN?

The pressure is expressed by the formula:
P = F / S, where P is the pressure (P = 1 kPa = 1 * 10 ^ 3 Pa), F is the pressure force acting perpendicular to the surface (F = 5 kN = 5 * 10 ^ 3 N), S is the surface area (m ^ 2).
Let’s calculate the surface area:
S = F / P = (5 * 10 ^ 3) / (1 * 10 ^ 3) = 5 m ^ 2.
Answer. You need a surface area of 5 m ^ 2.
