Historically a stack of paper would be up to the ceiling - so how high is the ceiling?
It would take 20 pieces of 3 mm thick paper to make a stack that is 6 cm thick. This is because 1 cm is equal to 10 mm, so each piece of paper adds 3 mm to the height of the stack.
43 stacks and one third of a stack.
The answer depends on how small (or big) the pieces of paper are!
200,000 pieces of paper are in a ton

A stack is a region of memory that you store things, and retrieve them in the reverse order of storage. Think of it as a stack of papers. You write something down on a piece of paper, and then you put that paper in a stack, specifically on the top of the stack. This is called a push operation. If you want to go and do something else, such as service an interrupt or call another function, you create more pieces of paper and you push them onto the top of the stack as well. Under normal conditions, you cannot access anything on the stack below the top. I say "normal" because the architecture of the processor allows you to access chunks of memory contained within the stack, relative to the base pointer BP, allowing you to pass arguments and store temporary variables in what is called a stack frame. The reverse of push is called pop, and it is equivalent to taking a piece of paper off of the top of the stack and throwing it away - or using it, whatever you want - but that action exposes the next piece of paper, which is now the new "top of stack".

If you fold a piece of paper in half 50 times, you would get a stack of paper so thick that it would reach the sun and back multiple times, with a thickness much larger than the observable universe. It's a theoretical concept as it exceeds physical limits.
The collective nouns for paper are a pad of paperand a ream of paper.
