Not really.
I'm might sound a bit of off topic here I but I consider both of
these as 'cheapo' tricks that only sound good on paper (and to
reporters): 'Look Ma the man can compute the sum of two cubes
in a flash'
1**3 is 1, all he needed to know is that 12**3 is 1728
Similarly knowing that 10**3 is 1000 is trivial, all he
needed to know is that 9**3 is 729.
Just as with squared values whenever one works with cubes
they will tune very quickly in and start recognize the first
20 or so by heart in a matter of minutes...
