Question

a polyhedron has 15 edges 10verticies find faces​

Answer 1

Answer:

A polyhedron has 5 faces

Answer 2

Answer :

• Faces is 7

Given:

• A polyhedron has 15 edges and 10 vertices

To find :

• Faces

Solution :

Given,

• Edges = 15
• Vertices = 10

According to Euler's formula we know that,

• V - E + F = 2

Where,

• V is number of vertices
• E is number of edges
• F is number of faces

So , According To this formula we have to find the faces

⇢ V - E + F = 2

⇢ 10 - 15 + F = 2

⇢ - 5 + F = 2

⇢ F = 5 + 2

⇢ F = 7

Hence , Faces is 7
