Change the shape according to the shape of the container. So whether your two asses are the same or not
As long as two containers are the same, it means that their capacities are equal.
The water pressure at the bottom can only be calculated by PGH.
Formulas derived from regular objects can be applied to irregular shapes, which is a conservation.
Is the physical quantity used in your formula a physical quantity that only irregular objects can have? Don't be too rigid. The formula of regular objects can't be changed into irregular physics, so it's no longer a formula, right?
For example, if a person is disabled, can't the medical methods tested on normal people be applied to him?
"In any container, must the pressure of water in the container at the bottom of the container be lower than the pressure of the container (including water) on the horizontal plane?"
This can't be said that physics is not absolute, but it should be judged according to the conditions he told you.
PS: Many physics books are experiments conceived in an ideal state. Treating liquid as a cylinder is just a way of thinking. The essence of water has not changed ~ ~
