Define Euler’s relation between the number of faces,
Question:

Define Euler’s relation between the number of faces, number of edges and number of vertices for various 3-dimensional figures.

Solution:

The Euler’s relation for a three dimensional figure can be expressed in the following manner:

$F-E+V=2$

$H$ ere,

$F-$ Number of faces

$E-$ Number of edges

$V$ – Number of vertices
