1 pound per square inch (psi) is the pressure created by a column of water __________ feet high.

2.31
3.14
4.71
6.28

The correct answer is: 2.31

1 pound per square inch (psi) is the pressure exerted by a column of water that is 2.31 feet high. This is because pressure is directly proportional to height, so the higher the column of water, the greater the pressure it exerts. Option B, C, and D all have incorrect values for the conversion factor, so they cannot be the correct answer. Therefore, option A is the most accurate choice.
