… and for today’s mathematics tutorial: the 8 bits correspond to the binomial expansion of (a+b) cubed. That is:
(a+b)(a+b)(a+b) = a-cubed + 3 (a-squared)b + 3a(b-squared) + b-cubed
More abstractly, with the ^ symbol as exponent:
(a+b)^3 = a^3 + 3(a^2)b + 3a(b^2) + b^3

Without the angled cage, this is the type of puzzle I would bring to the classroom, to demonstrate the connection between 3D geometry and the binomial expansion of (a+b) cubed.

In reply to Allard. Thanks Allard for pointing it out to me.

Nice puzzle (and post). I like the looks of those off-kilter windows.

Hi
I agree with your comments, it is real a nice and intriguing puzzle, real not too hard but is costs time to solve the cube inside
