that's cos only if they're round would it be impossible for the cover to drop through the hole. it's simple physics really. as long as the diameter of the cover is more than that of the hole, no matter how you orientate the cover, it'll never be able to drop through the hole. hope that answers your question. =)

I hear this is a very important question they ask you when you're applying for an MBA!

triangles won't fall too right?

even triangles can fall through the hole when you orientate them in certain positions. =)

I think round one takes less area & has better orientation as compare to square & Triangle.

That would depend on what kind of a triangle it is...
An equilateral one may not fall in....but others could
