Cuboctahedron

What is the magic number?

Let the width of the quasi-cube (and the length, and the height) = w
w is equal to what?
Semi-Quasi-Cube Each semi-quasi-cube is made up of four tetrahedra. Each tetrahedron has six edges. Let the length of each edge = x. How does x relate to w?
What is the magic number? (in inches)

According to Pythagoras: x²+x² = w²
w = (√2)x

x=length of edgesw=width of quasi-cube
1521.2
1622.6
1724.0
1825.4
1926.8

17 is the magic number because if we make all the edges and the vectors equal to 17"
then the width/length/height of each quasi-cube is 24" and the thickness of one semi-quasi-cube is

one linear foot!
