Yes, this is similar to another question, but, judging from the answers, maybe the OP wasn't clear enough in their question. According to the TSA's 3-1-1 rule, you can bring (in your carry-on baggage) as many 100ml containers of liquid that you can fit into a 1-quart (20mmX20mm) bag.
My confusion is this: If I can put the same liquid in each 100ml container, then the 100ml isn't a limit in any meaningful way; the 1-quart bag is. What is the rationale for letting me bring a bag of, say, four 100ml bottles of something but not one 400ml bottle?
The answer cannot be "Because 100ml of some explosive/corrosive liquid is not enough to harm the aircraft" because, from above, you can bring aboard probably 400-500ml of it in separate 100ml bottles in the same 1-quart bag. It can't be "Because, separately, they don't pose a threat" because one could mix them in any of the large empty containers they can bring through. The answer also can't be "Because TSA needs concrete, simple rules", since it would be simpler to just say "Whatever liquids you can fit into a 1-quart baggie" (i.e. a "1-1" rule instead of a "3-1-1" rule).
Seriously, what's the point?
