# What is the name of the base when the prism has 12 vertices?

An hexagonal prism would fit the given description

### How many vertices does a hexagonal prism have?

A hexagonal prism contains 12 vertices. If faces are all regular, the hexagonal prism is a semiregular polyhedron. This is the fourth in an infinite set of prisms formed by square sides and two regular polygon caps. The shape has 8 faces, 18 edges, and 12 vertices. ----------------- An n-gonal prism has 2n vertices. 6 at each end = 12 It has 12 vertices in total

### How many vertices does octahedron have have?

An octahedron is the name for a non-specific shape. It could be a di-rectangular pyramid with 6 vertices - this is like two rectangular [or square] based pyramids stuck together base-to-base. Or it could be a heptagonal pyramid, in which case it has 8 vertices. Or it could be a hexagonal prism, in which case it has 12 vertices. There are other octahedraons.

### How many faces vertices and edges does a icosahedron has?

An icosahedron is a polyhedron with 20 faces. The number of vertices and edges is indeterminate because there are many possible configurations. Three examples: A pyramid with a 19-gon base: 20 vertices, 38 edges. A dipyramid with a decagon base: 12 vertices, 30 edges. A prism with 18-gon bases: 36 vertices, 54 edges. An icosahedron is a polyhedron with 20 faces. The number of vertices and edges is indeterminate because there are many possible configurations…

### How many faces vertices and edges does a hexagonal prism oCtagonal prism n-gonal prism triangular pyramid rectangular pyramid pentagonal pyramid hexagonal pyramid n-gonal pyramid?

Name Edges, Faces, Vertices Hexagonal Prism 18, 8, 12 Octagonal Prism 24, 10, 16 A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. Triangular Pyramid 6, 4, 4 Rectangular Pyramid 8, 5, 5 Pentagonal Pyramid 10, 6, 6 Hexagonal Pyramid 12, 7, 7 A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.

### How many edges if there is 10 faces and 12 vertices?

A prism with 10 faces would have 16 vertices. A pyramid with 10 faces would have 10 vertices. Since your figure is neither of these, you need to tell us what it is. In case your numbers were incorrect, here are the formulas: 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…

### How many corners and faces does a docecahedron have?

A dodecahedron is 3-dimensonal shape with 12 faces. There are 6,384,634 topologically distinct convex dodecahedra, excluding mirror images, having at least 8 vertices (corners). Some examples: A pyramid with a 11-gon base (12 vertices). A bipyramid with a hexagon base (8 vertices). A decagon-based prism (20 vertices). A pentagonal antiprism (10 vertices). A regular decagon (20 vertices).
