Which polyhedron has the least number of faces?
A TETRAHEDRON, which is commonly referred to a a triangular based pyramid. The jokingly, a sphere. It has two faces, and outside face and an inside face, Ha!!!Ha!!!
What are the fewest faces a polyhedron can have?
4The minimum number of face a polyhedron can have is four.
What is a polyhedron with the fewest number of faces?
The Platonic solids, in order of number of faces, are:Tetrahedron - 4Cube - 6Octahedron - 8Dodecahedron - 12Icosahedron - 20Therefore, the fewest number of faces of a Platonic solid can be found on a tetrahedron.
What shapes are polyhedrons?
Polyhedrons are three-dimensional shapes with flat faces, straight edges, and sharp corners, known as vertices. Examples of polyhedrons include cubes, pyramids, prisms, and dodecahedrons. These shapes have a closed surface and are made up of polygons, which are two-dimensional shapes with straight sides.
What special features does a triangular based pyramid have?
It is a polyhedron with the smallest possible number of faces or vertices.
Can a polyhedron be named after the number of faces?
Yes they normally are as for example a tetrahedron is triangular pyramid that has 4 faces
What is the base of the triangle in polyhedron?
A polyhedron is a 3-dimensional object comprising a space enclosed by a number of polygons. In general, these polygons are called faces: in some polyhedra they are also called bases. They may or may not be triangular. A pentagonal prism, for example, has no triangle face and so no triangular base.
What is the formula of surface area of a polyhedron?
There is no standard formula since a polyhedron can have a number of different shapes. A hexahendron, for example, can be a cuboid (6 rectangular faces) or a triangular dipyramid (6 triangular faces) or others. The number of different shapes increases rapidly as the number of sides (which determines the name) increases. The only solution is to calculate the area of each face and add them together.
How the names of the polyhedrons help you to know the number of faces?
In the same way that knowing the names of polygons helps you to know how many sides it has. Polygon means many sides and polyhedron means many faces
What is the difference between a tetrahedron and a triangular prism?
A tetrahedron is a polyhedron with four triangular faces, while a triangular prism is a polyhedron with two triangular faces and three rectangular faces. The main difference between the two shapes is their number of faces and their base shapes. Additionally, a tetrahedron has four vertices and six edges, while a triangular prism has six vertices and nine edges.
Is a triangular pyramid a regular polyhedron?
A triangular based based pyramid is a TETRAHEDRON. It becomes a regular tetrahedron if the four triangles, that make up its shape, are REGULAR, that is they are all the same size by area and shape; that is they are congruent. The word 'polyhedron' means a solid shape of any number of sides.
Name the faces of the 7 sided polyhedron?
There are a number of possible 7-sided polyhedra. Three that come immediately to mind are: a hexagonal pyramid, a pentagonal prism, a "stretched" triangular pyramid (triangular base, rectangular sides, and then triangular faces meeting at an apex).
