A surface of which one end or side is at a higher level than another. source

Shouldn't it be "A surface one end or side of which is..."?

By your reply, can I assume it is inverted sentence?

It's not inverted like an interrogative sentence. I think a different syntactic term applies, but I'm not the right person to say.

Which grammar rule applies to it? As far as I understand, "of which" is an equivalent of "whose".

There are some contexts in which whose could substitute for in which. The sentence you quoted in post #1 is not one of them. Neither is the first sentence of this post.
