I have 3.5m need to buy 184 stacks of boxes its 65.000 for four stacks of boxes how much will that?

I can't even figure out what your question is. An "m" is an abbreviation for million, but a lot of people think it means thousand. In the USA a period means a decimal, but in other countries it is used where Americans would use a comma. So your question is meaningless until you explain it better.
