VIDEO TRANSCRIPT
This is Giancoli Answers with Mr. Dychko. The pressure exerted by a column of fluid is its density times g times the fluid column's height. Atmospheric pressure won't matter because it's the same on both ends of the column and so it just cancels out so this formula won't do the trick for us. We have 1.00 times 10 to the 3 kilograms per meter cubed times 9.8 newtons per kilogram times 46 meters which gives 4.5 times 10 to the 5 pascals.
