A box weighing 700N exerts a pressure of 7kPa on the support. determine the area of the support.


F = 700 Newton – box weight;

P = 7 kPa – the pressure that the box exerts on the support.

It is required to determine s (square meter) – the surface area of the support.

Convert pressure units from kilopascals to Pascals:

P = 7 kPa = 7 * 10 ^ 3 = 7 * 1000 = 7000 Pascal.

Then, to determine the area of the support, you must use the following formula:

P = F / s, from here we find:

s = F / P = 700/7000 = 7/70 = 1/10 = 0.1 square meters.

Answer: The support area is 0.1 square meters.
