If a solid has 5 faces and 6 vertices, then it has:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 9 edges
For any solid with flat faces (a polyhedron), Euler’s formula links the numbers of faces, vertices and edges: \(F+V-E=2\).
\(5+6-E=2\)
\(E=9\)
Such a solid is a triangular prism: two triangular ends joined by three rectangular faces.
