Whilst many don't subscribe to the idea of time as being equivalent to a spatial dimension, it's something that got me thinking the other day.

If I have in my possession a square of 1metre side (yes, the 2-dimensional object and not some kind of square frame etc) - how long does it have to be in existence to be a cube?

My initial guess is that the speed of light in a vacuum defines the relationship between distance and time - so 1/299792458 of a second. Does anyone have any other theories? Could it be the delightfully SI answer of one second? I'd be interested to hear.
