Question

verify the Euler's formula for octahedron

Answer 1

Euler's Formula
For any polyhedron that doesn't intersect itself, the

Number of Faces
plus the Number of Vertices (corner points)
minus the Number of Edges
always equals 2



This can be written: F + V − E = 2



Try it on the cube:

A cube has 6 Faces, 8 Vertices, and 12 Edges,

so:

6 + 8 − 12 = 2
