Stand "In" the back or "at" the back?

[chibe_k]

Hi Teacher,

What is the correct preposition to use with the word "back"? For example,

1. Stand "in" the back...
2. Stand "at" the back...
3. Stand "in" the front...
4. Stand "at" the front...
5. Stand "at" the side...
6. Stand "on" the side...

Which sentenses are the correct ones? I am confused with the usage. Thanks in advanced ;-)

These differences are mostly differences in regional dialects and conventions of usage. All of them are correct English grammar.

There are, as Mike noted, some specific situations or some dialect differences.
Generally, we use 'in' for an enclosure type situation; car, room, closet, etc. and we use 'at' for a position or space or location.
