Number of faces, edges and vertices in the given figure

Solution:
Every individual flat surface of a solid is called its face.
In this figure, there are 14 faces.

The line segment which acts as an interface between two faces is called an edge. Sometimes it is also described as the line segment joining two vertices.
In this figure, there are 36 edges.

The formal definition for the vertex meaning in Maths is defined as a point where two or more edges meet. Vertices are the corner points.
In this figure, there are 24 vertices.
