It's not possible to determine exactly how many ants could fit inside an elephant, as it would depend on the size and shape of the ants as well as the size and shape of the elephant.

However, it's safe to say that the number of ants that could fit inside an elephant would be significantly greater than the number of elephants that could fit inside an ant. This is because ants are much smaller than elephants and can fit into spaces that would be much too small for an elephant to enter.

It's worth noting that this question is purely theoretical and has no practical application. Ants and elephants live in different parts of the world and do not interact with each other in a way that would allow one to be placed inside the other.
