## Homework Statement

The ocean liner Titanic lies under 12500 feet of water at the bottom of the Atlantic Ocean. (The density of water is 62.4 lb/ft{}^3.)

What is the water pressure at the Titanic? (Give your answer in both pounds per square foot and pounds per square inch.)

## Homework Equations

pressure=ro*g*h

## The Attempt at a Solution

at first, all I did was multiply 62.4*32(g in ft/s^2)*12500. The answer was wrong and then I think I found out why. I multiplied the units (lb/ft^3)*(ft/s^2)*ft and got lb/(ft*s^2) instead of lb/ft^2. Anyone get what I'm supposed to do for this problem? I never had this problem when working with metric units since kg/(m*s^2) converts nicely to N/m^2 Thanks!
