If the cardboard measures by
---------------------
No dimensions.
-----
A general solution, with dim's x by y and the squares removed are z by z in any units.
----
Volume = z*(x-2z)*(y-2z) --- x & y are constants, the given dim's
Vol = z*xy - 2z^2*(x+y) + 4z^3
dV/dz = xy - 4z*(x+y) + 12z^2 ---- 1st derivative of volume wrt z
-------------
12z^2 - 4z*(x+y) + xy = 0
z = 4(x+y)/24 + sqrt(16(x+y)^2 - 48xy)/24
