Greatest Area

Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.

A farmer challenges an engineer, a physicist, and a mathematician to fence off the largest amount of area using the least amount of fence.

The engineer made his fence in a circle and said it was the most efficient.

The physicist made a long line and said that the length was infinite. Then he said that fencing half of the Earth was the best.

The mathematician laughed at the others and with his design, beat the others. What did he do?

Great one. I was a math major in college, so I like that the mathemetician was the most clever in the bunch.

This is actually off a science jokes website. Nonetheless it is still very nice.

I don't get it!

If the mathematician is on the outside, then all land on the other side of the fence (which is the entire world) is on the inside.

A little confusing at first but clever once you get it! I thought the line was infinite though...

I love it! Oh, Ilove it!!

I so got that! It's nice to know I'm smarter than an engineer and a physicist

I love that one, i like math and so i am glad that the mathmetician was the smartest one, and i especially liked when he laughed at the others

That was great, but it took me a second to get it!
If he said he was on the outside, then his fence covered the rest of the world! Clever

I hope he put a gate so he could get back in!
craniacAus*
Oct 29, 2007

Got it, except in my version, the mathematician had the good sense to put himself on the inside when he built his fence.

Sorry but this riddle is very old and time worn
auntiesisAus*
Oct 29, 2007

This riddle may be an old one, but I never heard it. As a math freak, I'm happy to say I got the answer even before I finished reading the teaser.

all
avonmaAus*

I thought that was a hard one, but only because I didn't get it. I liked it, though, because it was so clever! (By the way, it was new to me)

I love MATH!!!
this was a cool teaser.
dstarbirdAus*
Oct 29, 2007

I was close. I thought he put up a single post and said everything outside it was fenced.
mondayschild59Aus*
Oct 29, 2007

If the line was infinite it still only seperated the world in half. I like this teaser. It was very hard and I didn't get it right, but I still like it.

Having the farmer asking the
question threw me off. They were
fencing the earth, maybe if God
asked the question I might have
gotten on the right track.

Didn't get it.
drussel3*us*
Oct 29, 2007

That's thinking OUTSIDE THE BOX... Great One
breathesunshineAus*
Oct 29, 2007

I wanted to like it but found myself feeling like it was a "groaner" instead of clever. However the majority seem to really have liked it so maybe I'm just tired and need to go to bed!

that was funny and obvious I liked it

Hey, it was a clever one.
But I knew about it from a scientist joke site, where all jokes were about different sciences/professions.

That was hysterical and had me laughing for hours! Well, minutes, I kinda move along after a few minutes... Loved it though!

That is straight out of Douglas Adams' books.
Wonko the Sane turned his house inside out, called it the Asylum and declared that the world was in the asylum and he was the only person living outside it in the real world!

There's nothing really new, is there?

pretty good!!
Queen_Nesh7Aus*
Mar 27, 2008

I liked this ! since he was on the outside of the fence then the inside of the fence covered the rest of the world and it took up the least amount of fence but covered the most land!!

i really enjoyed this one. it was different, which is uncommon.

Although I got this one, I had never heard it before. Most of the riddles on this site are either "old ones" or are ones slightly modified from our memory, so it should not be pointed out how "old" some of these are... they are still around because they are classic and many of us have still never heard them.

Although the mathmatician did fence off the greatest amount of surface area between the three, there is a more efficient option. Which would be to use NO fencing. This would yield the greatest amount of surface area whilst using the least amount of fence. O Whored. Think about it deg. maybe next time chief.

Hmmm... I don't get it...

It is brilliant. Easy but the point made is briliant.

And Rastamon: the framer challenged them to fence off the largest area - using no fencing would result in them not fencing off anywhere.
woodrock96Aus*
Feb 03, 2010

I was thinking that he used no fencing. But, after seeing the answer, I completly understood why I was wrong. This is Brilliant!

I think the physicist and mathematician are switched. Mathematicians always have infinite lines and physicists are always talking about different frames of reference. still, same joke. fun. ok.

how long did it take for the phystic to build his fence?

i was able 2 solve it

Aug 15, 2012

I had never heard this, but still found it very easy. Really, the only logical thing to do. However, I am not sure why it was the mathematician who came up with the idea. I guess it could just as easily have been a blonde, brunette, redhead...

Still love this teaser. I totally forgot about it, but the answer came to me just as quick as a wink.
