Dissection of a Cube to a Quarter of a Rhombic Dodecahedron of the Second Kind
Initializing live version
This Demonstration shows the dissection of a cube into four pieces to give a rhombic dodecahedron of the second kind.
The volume of the dodecahedron is /2, where d is the larger diagonal of the golden rhombus. So the edge of the cube has length d/2.
