কীভাবে Octahedron গণনা করবেন
Octahedron কি?
A regular octahedron is one of the five Platonic solids, with 8 equilateral triangular faces, 12 edges, and 6 vertices. It looks like two square pyramids joined at the base.

সচরাচর জিজ্ঞাসা
Why is the octahedron called a Platonic solid?
It's one of five Platonic solids: all faces are congruent regular polygons, and the same number of faces meet at each vertex.
How many vertices, edges, and faces does an octahedron have?
The octahedron has 6 vertices, 12 edges, and 8 equilateral triangular faces.
What is the dual polyhedron of an octahedron?
The cube (hexahedron) is the dual. Its vertices correspond to the octahedron's face centers.
