11 Squares Puzzle

This is a math puzzle based on the currently known optimal packing for eleven squares inside of another square. The math of optimal packing is super cool, and I think it's awesome that such interesting examples can be 3D printed so easily. Good luck and happy solving! Fun fact: the side length of the large square is approximately 3.887 times the side length of the inner squares. The exact number is a root of the equation s^8 - 20s^7 + 178s^6 - 842s^5 + 1923s^4 - 496s^3 - 6754s^2 + 12420s - 6865 = 0.
