Dimensions in popular culture

[ptc24]

No, not alternate realities, actual dimensions of things. A 2x4 is useful for hitting people with, and of course everyone should know the significance of 1x4x9. But surely there are others that I can't think of...

ETA: OK, there are lots of things which are kind of one dimensional. But how about things which are 2D or 3D like the examples above (or tim's example)?

Hmmm, those aren't dimensions as such (certainly not in the four wheel drive case, I don't know of others).

Hm, how about 5x5? :)
