Question

Find the number of edges of a polyhedron having 14 vertices and 9 faces, and also name the polyhedron.

Answer 1

cylindrical is the answer

Answer 2

Number of edges of a given polyhedron = 21

Step-by-step explanation:

• Given that, the polyhedron has 9 faces and 14 vertices.
• From Euler's formula No. of edges, E=F+V−2
• Substituting the values ⇒E=9+14−2 ⇒E=21
• Heptagonal prism is the name of this polyhedron.
