How many vertices does an icosahedron have?
There is no simple answer to this question.Polyhedra are named according to the number of faces that they have. An icosahedron is a 3-dimensional shape with 20 faces. It could be in the form of a pyramid with a 19-sided polygon as base. In that case, it has 20 vertices. Or it could be in the form of a prism with 18-sided polygons as base and in that case it has 36 vertices. There are several million different configurations, and the number of vertices varies.The regular icosahedron is a Platonic solid with faces that are equilateral triangles. That has 12 vertices.
How many vertices does a 3-D octagonal prisms?
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. 16 vertices
How many vertices does a 3 sided triangle have?
All triangles have three vertices.
What 3 expessions show a pyramids number of faces and vertices and edges?
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
Which has more verticles a shape with 4 sides or a shape with 3 sides?
A 4 sided shape has 4 vertices whereas a 3 sided shape has 3 vertices.
Which has more vertices a shapr with 4 sides or a shape with 3 sides?
A 4 sided shape which is a quadrilateral has more vertices than a 3 sided shape which is a triangle
How many vertices do 3 hexagons have?
A 6 sided hexagon has 6 vertices and so 3 hexagons will have 3*6 = 18 vertices
What solid figure has 2 base 3 other faces 9 edges and 6 vertices?
It is a triangular prism.
How many edges and vertices a pyramid has?
A pyramid is a generic mathematical term which is used to describe a 3-dimensional shape which consists of an n-sided polygonal base and n triangular faces meeting at an apex. If the pyramid has an n-sided polygon as base, then it has 2n edges and n+1 vertices (and n+1 faces).
How many vertices does 3 sided pyramid have?
5 edges
What is a solid 3 or 4 sided figure?
There cannot be a solid three sided figure. A solid 4 sided object is a tetrahedron.
How many faces are on a 3-dimensional triangular pyramid?
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
