SUMMARY

The discussion centers on the geometric relationship between an octahedron and a cube, specifically addressing the claim that an octahedron cannot exist within a cube. Participants express confusion over the validity of this assertion and the clarity of the question posed. The consensus leans towards the idea that an octahedron can indeed be inscribed within a cube, as the vertices of the octahedron can align with the midpoints of the cube's faces.

PREREQUISITES
  • Understanding of basic geometric shapes, specifically cubes and octahedrons.
  • Familiarity with spatial reasoning and visualization techniques.
  • Knowledge of geometric proofs and properties of polyhedra.
  • Basic skills in drawing geometric figures for clarity.
NEXT STEPS
  • Research the properties of polyhedra, focusing on the relationship between cubes and octahedrons.
  • Explore geometric proofs that demonstrate the inscribability of an octahedron within a cube.
  • Learn about spatial visualization techniques to better understand complex geometric relationships.
  • Investigate software tools for 3D modeling to visualize geometric constructs.
USEFUL FOR

Students of geometry, educators teaching geometric concepts, and anyone interested in the properties of polyhedra and spatial reasoning.

I heard somewhere that the Octahedron can't exist in the Cube exactly.

Is this true? Can't I prove that the octahedron in the cube?

Intuitively, they seems true. But I can't sure.

Your question is not at all clear.

I meant this. I heard that this octahedron don't exist. But...
 
You are both drawing something and telling us it can't exist. Doesn't that bother you?
