1) The document analyzes the mathematical properties of a truncated hexahedron (cube) which is generated by truncating the vertices of a regular cube.
2) It derives formulas to calculate key properties like edge length, normal distances, solid angles, volumes, surface area, radii and more using principles of right pyramids and HCR's theory of polygons.
3) Two methods are described for constructing a physical truncated hexahedron either from elementary right pyramids or by machining a solid sphere.
