Answer:

Step-by-step explanation:
Given:
Exerts pressure

Piston has an area
![A = 168\ cm^{2]](https://img.qammunity.org/2021/formulas/physics/high-school/oveuzolnvqfs1719bl3zmxwz8w9kp9qt3u.png)
We need to find the force exerted by piston.
Solution:
Formula of pascals law's is given as:

Where:
F = Force applied
P = Pressure exerted
A = Cross sectional area
Substitute force and area in pascal's formula.

Using cross multiplication.



Therefore, the force exerted by piston
