A triangular prism has 9 edges, 5 faces and 6 vertices
3 more vertices
No, but it does have 4 vertices. It has 6 edges.
5 faces, 6 vertices, and 9 edges.
A triangular prism has 9 edges and 5 faces. It also has 6 vertices. A cube has 6 faces and 12 edges.
"Dose" is a measured portion of a medicine. I am not aware of any triangulars that have measured quantities of medication! Besides, the question does not state whether the question refers to a triangular pyramid, a triangular prism, icosahedron (20 triangular faced), or other polyhedron.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 6 - 5 = 1 more
Not sure that a triangular prism dose anything since a "dose" is a measured portion of a medicine. However, a triangular prism does have two bases.
A vertice is defined as where two or more edges meet. A hexagonal pyramid has a hexagon base and six triangular sides, giving seven vertices.
Triangular Prisms don't have any vertical edges
None. A non-existent pyramid has no vertices.
