Q: So, since I just got 24 of these bricks and all 8 corners on box r wrinkled means that many brick's r Damaged ?? At 12 bucks a brick ?

These bricks are very brittle and damage easily.

Q: Can i use this to make an ant formicarium? Is this aac/ytong block?

It's not aac/ytong but it's pretty much as close as we can get in the states. From what I hear it's very similar and you could make a nest out of it the same way you would ytong. Go for 2600F if you have a species that may chew through the material like Camponotus. (I'm also looking at using this to make my first formicarium ^^)

Q: How many come in a pack??

It depends on which pack you select. They come in single, 2-pack, 4-pack, and 12-pack sizes.

Q: I need something to lift my small kiln away from a wood class floor and make the floor safe. will this work for that?

Yes, and I would combine it with a superwool board to make sure there is no radiant heat reaching the floor under the kiln. Link to board is below. https://www.amazon.com/Lynn-Universal-Baffle-Board-Superwool/dp/B0716M86PQ?ref_=ast_sto_dp&th=1&psc=1
