1. a large vertical rectangular plate of glass is to be inserted in the wall of an aquarium underwater so visitors can see into the tank fo fish. the glass is 10 feet high, 25 feet long and the top fo the glass is 3 feet below the top of the water. The pressure exerted by water at depth b feet below the surface is .433b pounds/square inch. Your task is to set up the integral to compute the total pressure of the water (in pounds)against the glass.

2. What fraction of the pressure if exerted against the bottom half of the glass?
