Quick Answer: What solid figure has 12 edges?

What is a shape with 12 edges?

In geometry, a dodecagon or 12 -gon is any twelve-sided polygon. Dodecagon.

What is the name of a solid with 12 edges of equal length?

The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.

What Prism has 12 edges?

In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. Hexagonal prism.

What 3d figure has 12 edges?

A cuboid has 12 straight edges, which are the lines between the faces. A cuboid has 8 vertices, which are its corners where the edges meet. A cuboid has exactly the same number of faces, edges and vertices as a cube.

What 3D shape has 20 faces 12 vertices and 30 edges?

Icosahedron: 20 faces, 30 edges, 12 vertices.

What shape has no edges or vertices?

A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices.

What is a three dimensional hexagon called?

A 3D hexagon is called a hexagonal prism. It has two hexagons for bases and six rectangular sides. A hexagonal prism is classified as an octahedron, which is a three – dimensional geometric object with eight faces.

What 3D shape has 9 edges?

Pentahedron

Does a cone have edges faces or vertices?

A face is a flat surface. An edge is where two faces meet. A vertex is a corner where edges meet. Vertices, edges and faces.

How does a rectangular prism have 12 edges?

Rectangular Prisms It’s made up of 6 rectangular faces. When you join the sides together, it becomes a rectangular prism with 8 vertices and 12 edges.

What will be the number of edges if there are 12 vertices and 20 faces?

Answer. Answer: According to the formula given by Euler. Therefore, there are 30 edges of a polyhedron having 20 faces and 12 vertices.

Can a polyhedron have 10 faces 20 edges and 15 vertices justify?

No.It can ‘t have 10 faces, 20 edges, and 15 vertices as The formula i.e. Euler’s formula isn’t being satisfied. Therefore,A polyhedron cannot have 10 faces, 20 edges, and 15 vertices.

Do 3D shapes always have more edges than faces?

A cube has 6 faces and 12 edges, so a square-based pyramid must have 5 faces and 10 edges. The number of edges is always double the number of faces. 3D shapes always have more edges than faces.

What is the 3 dimensional figure shown?

A cube, rectangular prism, sphere, cone and cylinder are the basic 3 – dimensional shapes we see around us.

What 3D shape has 7 faces 15 edges and 10 vertices?

In geometry, the pentagonal prism is a prism with a pentagonal base. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.
