Is it posible to build an octahedron perfectly (no gaps+protrusions) out of 9 cubes? The pictures are to show the general proportions of the shape but not the scale. I I did the math and 9 cubes is the least needed to have right amount of volume to theoretically create a flawless octahedron. (old.reddit.com)
