Given that this stands out a mile as almost certainly a school homework question, to answer directly would be to make me complicit in cheating.
So I will tell you how to calculate it, which would appear to be the point of the question:
1) The relationship between depth and pressure of water is linear.
2) If water X ft deep exerts a pressure of P lb/in2, then water of Y ft deep will obviously exert a pressure of P(Y/X) lbs/in2
Given thats information you can now solve the original question.
12psi
12.01 psi
20 pounds per sq/in
The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).
mass / area although technically it should be weight (or force) / area for example: imperial an object with a mass of 1.5 lb and an area of 2 square inches will exert a pressure of 0.75 pounds per square inch (psi) metric an object with a mass of 1.5 kg and an area of 0.5 square metres will exert a pressure of 3 kg/m2 (or 3 N/m2 or 3 Pa)

A column of air exerts atmospheric pressure on the air or surface below it. This pressure is caused by the weight of the air above pushing down on the lower air or surface.
The same reason bricks exert downward pressure. Gravity.
Yes, water exerts pressure on the hull of the submarine.
The same reason bricks exert downward pressure. Gravity.
Ice exerts a pressure of around 35,000 to 40,000 pounds per square inch in a pipe. This pressure is due to the expansion of water when it freezes, causing the ice to exert a significant force on the walls of the pipe.
Sorry - it exerts more pressure than a flt heel.
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
You need to know how high the water column is to calculate the pressure it exerts at its base! For example, a column of water 1 metre deep would exert a pressure of 9.81 kPa at its base (density x gravity x depth - 1000 * 9.81 * 1). This would be equal to approx 1.42 PSI.
An ordinary human standing exerts a pressure equivalent to the body weight divided by the area in contact with the ground. On average, this pressure is about 10-15 pounds per square inch (psi).
