Increasing (or decreasing) a block size
When I increase a block size from 6x6 to 12x12 -
doesn't it seem to be logical to say that I DOUBLE the size of the block? But actually, the area of the block will be QUADRUPLED! 6x6 = 36 12x12 = 144 Or the other way around - when I decrease a block size from 12x12 to 6x6 - it seems logical to me to say that I cut the size by half. However, the area of the smaller block is only 1/4 the size of the larger block. 12x12 = 144 6x6 = 36 |
Which is why it takes (4) 6 1/2" squares to make (1) 12" block...often people do not realize this until they try to just double everything, then wonder why it's not working. Glad you realized it. :)

The doubling is of the square formed by the diagonals of the four inset squares. Socrates explained it best.

Anything for you, Bear! :)

Isn't math marvelous? :thumbup:

Yes, it is, Neesie. And I love your Dawkins' quote.
