Concept of Hidrostatic Pressure in Random Shaped Vessel

In summary, the conversation discusses the concept of hydrostatic pressure and how it is affected by the depth of a liquid in a container. The best answer is determined to be Pz > Px > Py, but it is not listed as an option in the question. The shape of the container does not affect the pressure at each point and the conversation suggests that there may be a mistake in the book's answer. The total pressure at each point is calculated by adding the atmospheric pressure to the product of the liquid's density, gravity, and depth.

Homework Statement
[Translate to English]
Look at the following picture, the true statement is?
Relevant Equations
Hidrostatic Pressure - P = rho . g . h
Hello Everyone!
this question is using Indonesian language, i have translated the question at "Homework Statement". The container is filled by water (in Indonesian, "Air" means "Water")

i know the the pressure at point X, Y and Z depends on their corresponding depth. my best answer is :

Pz > Px > Py

But the answer is not available in the question, I'm wondering the shape which point Y and Z have something to do with the answer. I'm hoping you guys give me the basic concept of Hidrostatic Pressure regarding of this question. Thank you!

Hello @Vermilion X ,
:welcome: !​

Your best answer is my best answer. I expect there is a mistake in the book answers.

Total pressure at each point is ##P_{atmospheric} + \rho g h##
The shape of the container does not affect this.

So your answer is correct. ##P_z>P_x>P_y##. This is not in the list of answers.

However, the diagram may be badly drawn - perhaps x and y are meant to be at the same height. That would give answer ‘a’.
