The strongest shape for withstanding water pressure is a sphere. This is because water pushes the same amount on every side of an object. A sphere is an object that has the same shape on every ’side’, so there are no weak points. So a window in a submarine would be shaped like a sphere, or a section of one. (Unless the submarine was never going to go very deep, in which case the windows wouldn’t need to be as strong.)

For another way that the spherical shape is used in building a submarine, take a look at the answer to .
