Question

ii- Faces=4 , vertices = q , Edges=6
using Euler's formula , find the unknown quantity . Also , identify the solid based on the information available ​

Answer 1

Answer:

$Hello!$

$euler's$  $formula = F+V=E+2$

here,  

        faces (F) = 4,

        vertices(v) = q,

         edges (E)= 6.

  therefore,    4+q = 6+2

                         q  = 8 -4

                          q= 4.

∴  no of vertices = 4.

From the available data, we can conclude that the solid shape is a triangular pyramid.
