What shape has 8 triangular faces ans 12 edges?
It is an octahedron which is one of the Platonic Solids having 8 equilateral triangular faces and 12 edges.
The two solids are similar and the ratio between the lengths of their edges is 3 8 What is the ratio of their surface areas?
9:64
What two solids has the same amout of vertices?
A cube and a cuboid of which both have 8 vertices, 12 edges and 6 faces
How many edges does a platonic solids have?
There are different numbers on the different platonic solids.
What solids do not have any faces or edges?
spheres
Which 2 solids have the same number of edges?
A rectangular prism (cuboid) and a hexagon-based pyramid, for example, both have 12 edges. Of the five Platonic solids, an octahedron and a cube each have 12 edges.
What solids have 12 edges?
A cube has 12 edges as does an octahedron and those are the two platonic solids (convex polyhedra with congruent regular polygons as faces where the same number of faces meet at each vertice) with 12 edges.
Why are platonic solids special to ordinary solids?
Symmetry. Perfect symmetry. Equality of angles, edges and vortices.
Which three types of solids do not have faces or edges?
Spheres
How many vertices and edges does a quadrilateral pyramid have?
5 vertices and 8 edges.5 vertices and 8 edges.5 vertices and 8 edges.5 vertices and 8 edges.
Which of the 3-D figures has the fewest edges?
a sphere has no edgesOf the solids with planar faces and line edges the tetrahedron has the fewest edges and faces. (Four faces and six edges)
What are regular Platonic solids and their properties?
There are only 5 known regular Platonic solids and they and their properties are:- 1 Tetrahedron: (pyramid) 4 equilateral triangle faces, 6 edges and 4 vertices 2 Hexahedron (cube) 6 square faces, 12 edges and 8 vertices 3 Octahedron: 8 equilateral triangle faces, 12 edges and 6 vertices 4 Dodecahedron: 12 regular pentagon faces, 30 edges and 20 vertices 5 Icosahedron: 20 equilateral triangle faces, 30 edges and 12 vertices All of them can be inscribed inside a sphere.
