This question already has an answer here:
So if the pressure in a large fish tank 10 meters below water surface is 50 Glitches (didn't have a realistic number so I put an unrealistic unit), and a Pancake batfish stands still there for a while, does it experience pressure equal to 50 Glitches? , The answer should be yes; by looking at the derivation of the formula $P=\rho gh$
This question was an alternate question to whether the Pressure on an object midway in a fluid depends on the area of the object or not, and the answer is No if I'm correct, but I also think that the pressure on the object depends on the area of the container, in other words if the batfish stand still for some more time and walls keep pushing towards it it will feel more pressure, but can't see the formula above saying anything about it, the derivation does though. What do you think?
