This is a fluid dynamic question. I'm very confused about this quesiton. Can anyone help me out with this question?
Thanks!

A research submarine has a 30.0 -diameter window 8.70 thick. The manufacturer says the window can withstand forces up to 1.20×106 . What is the submarine's maximum safe depth?

You first must find the water pressure as a function of depth. This is nominally rho*g*D, where D-depth and rho=sea water density (look it up). The force on the window is this pressure times the area of the window. The thickness spec isn't needed. This is only approximate, since ocean pressure is not linear. For an accurate answer, you need a table of sea water pressure vs depth. In any case, you calculate force from pressure the same way.
By the way you didn't give any units in your problem. it is very important to be consistent in units (30-what diameter? cm, in, ft?)
Force in newtons, dynes, pounds?. Without units there is no meaning.
