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.
Surface area of a cylinder (the column) = pi*diameter*height and measured in square units.
Pressure is defined as the following Pressure = force / area. So what this means is pressure is how much force is exerted over a area of given size. For examle a concrete slab is on the floor this slab has a width of 2m and a length of 2 m its area is 2 x 2 which gives 2m Squared. Its force it exerts is 1000 newtons ok what the hell does this mean? if you place this in the formula you will get pressure = 1000/4 Pressure = 250 newtons per square metre. I hope this answers you question on what pressure is.

Air (atmosphere) goes up to only a few miles from the surface of the earth. Imagine a column of air as felt on the surface of the earth. Every square unit of area experiences the force exerted by this enormous column of air. As you travel upwards the column of air above from that point up is smaller and so exerts less force per unit area. Force per unit area is pressure and that is why the pressure decreases as we travel up. To give you something you can relate to easily, the pressure at the bottom of a swimming pool will be more than the pressure half way up from the bottom because in the first case a larger column of water exerts its weight whereas in the second case it exerts only half the weight.
Every 2.3077 feet of water in a column increases the water pressure at the bottom of the column by 1 pound per square inch.A 39 foot column of water with a pressure of 120 psi at the base will have a pressure exerted on its top surface of 103.1 psi.39 ft/ 2.3077 ft/1 psi = 16.9 psi ; 120 psi -16.9 psi = 103.1 psievery meter of water in a column increases the pressure at the base of the column by 0.1 kg./ sq. cm (or 1 kilopascal)A 12 meter column of water exerts a pressure at its base of 12 kPa. (or 1.2 kg/sq. cm)
The pressure at 5400 feet underwater is approximately 2333 pounds per square inch (psi). At this depth, the water column above exerts a significant amount of pressure on any object or structure submerged at that depth.

An average human hug exerts about 10 pounds per square inch of pressure. This pressure can vary depending on the strength and duration of the hug.
One fathom of water exerts a pressure of approximately 64 pounds per square foot, which is equivalent to 1.42 pounds per square inch.
Assuming you are at sea level, the pressure will be about one atmosphere - or about one bar. (The pressure is the same for any area.)
The ratio of feet in the air to pounds per square inch of water pressure at the use point in a gravity water system is approximately 2.31 feet of elevation for every 1 psi of pressure. This ratio is based on the general relationship between water height (feet) and pressure (psi) due to gravity.
