 Oh no it isn't.  The cistern is not a cube.

Bugger 1.

 I'm not sure which side your s is.  If s is the side of the cistern,
then the height h is (1000000-s)/2, and v = s * s * h.  If s is the
side of the cut-off square, then the base b is (1000000-2*s) and
v = b * b * s.
 And of course the calculation overflows 32-bit ints.

Bugger 2!
Redoubled in buggers. I quit!
(For a few moments, at least.)
