Why Beauty Is Genius


Why Beauty Is GeniusOnce Geniusbeauty was asked:
– Why are you called Geniusbeauty? I see you’re beautiful, but why “Genius“? I’ve got a riddle for you, so if you solve it, you will prove me, that you are the real Geniusbeauty. Here is a heap of bricks. I’ll give you a slide rule and you will have to measure the diagonal of the brick. But remember, that you can measure it only once!

In the end she proved, that she was not only beautiful, but also smart. How did she do this? What did she answer?

Please, if you want to find the solution yourself, do not look at the comments of this post, because someone could have already written it there. You will find the solution in the next brain game. You are always welcome to ask questions about the task, in case something is not clear. But sorry, I will not answer leading questions. Good luck!

The answer to the previous brain game is:

4 9 2
3 5 7
8 1 6

Every row, column and diagonal is 15. If you rotate the grid, the logic stays the same. For those, who would like to find out the logic in detail, here is the link: http://en.wikipedia.org/wiki/Magic_square.
Congratulations to those, who solved it: Stargoat, Chris, Steve, Hj, Laurentiu Craciunas, Jed Hawk! Many thanks to Jed Hawk for the detailed explanation.
