Math Challenge #1 Answer to win SBD

in mathematics •  7 years ago  (edited)

If you have a piece of paper that is 0.1mm thick, how many times will you have to fold it in half in order for it to become tall enough to reach to the Moon?

Prize will be given after 7 days.

fold it 42 times

That's right

Actually correct answer is ~ 41.80575. If we are talking about average distance to the moon

you can find 'exact' number by using logarithm to base 2

it wont work...you cant fold a piece of paper more then 14 times

this is the correct answer... 8)

You are all wrong!!!!

The answer is clear. ZERO TIMES.

You are all assuming this paper is on earth. Where does it suggest that in the question?

My piece of paper (just like my crypto portfolio) is already on the moon. Keep folding away, you'll get here soon. lol.

By the way, this answer is more accurate than any other because at least it is physically possible to have a piece of paper on the moon. Folding a piece of paper 42 times is not.

I win, lol.

Your answer is creative. I'll consider it right. You are in the list of winners.

Hey thanks, @yuvi. I wasn't quick enough to do the math so I got creative. looking forward to the next competition so Ii can have a go at the actual math. Thanks again.

Distance from the Earth to the moon is 384400 KM.
Every fold multiplies the thickness by 2.
0.1 mm = 0.0001m = 0.0000001 km
384400/0.0000001 = 3,844,000,000,000

So 2^x = 3,844,000,000,000.
With some random guessing, as I don't know how to use log, here the answer is:
ANSWER = 42

(PS: It's in log2 41.8, but how'd you fold it 0.8 times?)

By the way, I don't think it's fair if the prize now goes to grizzman, as this explanation obviously made it take longer.

Good. Wait till the end of the 7 Days.

If you're not first, you're last. It's a great book.

That's nonsense. I had the answer earlier and could've replied saying only the answer, but I just did the whole explanation and it's just not fair xD

I don't really care about not getting 0.1 SBD though, it's nearly nothing, but I do care about the way people behave on this place.

I understand.

You got beat fair and square bud.

How did I get beat? I gave an explanation whilst the others didn't.

he asked for an answer, not an explanation. And you were not first to answer.

Didn't ask for the first one to answer though...

squeeze it ;)
