In a polyhedron, the number of faces is 4 and the number of edges is 6, then the number of vertices of that polyhedron is:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 4
For every polyhedron, Euler’s formula links the faces, vertices and edges: \(F+V-E=2\).
With 4 faces and 6 edges: \(4+V-6=2\)
\(V=4\)
A solid with 4 faces, 6 edges and 4 vertices is a tetrahedron (a triangular pyramid).
