WebNov 28, 2016 · At the n th level, we see that the square is broken into 4 n subsquares and the polygonal approximation to the ultimate space-filling curve consists of 4 n − 1 segments of length 1 / 2 n. Thus, the length of the approximating curve at stage n is ( 4 n − 1) / 2 n. This same approach can be used to find the length of the three-dimensional ...
