# How many faces does a 10 sided Decagonal pyramid have?

## How many faces does a 10 sided Decagonal pyramid have?

The decagonal prism has 12 faces, 30 edges, and 20 vertices, so, it is a dodecahedron (while the term is usually applied to regular dodecahedron or rhombic dodecahedron.).

**How do you find the volume of a Decagonal pyramid?**

For any pyramid with a regular base, you can use the equation: volume = (n/12) * height * side_length² * cot(π/n) , where n is number of sides of the base for regular polygon.

**How many sides does a Decagonal pyramid have?**

No. of faces | No. of edges | |
---|---|---|

(i) an octagonal prism | 10 | 24 |

(ii) decagonal pyramid | 11 | 20 |

### How do you find the volume of a decagonal prism?

Any prism volume is V = BH where B is area of base and H is height of prism, so find area of the base by B = 1/2 h(b1+b2), then multiply by the height of the prism.

**What pyramid has 11 faces?**

Dual polyhedron The dual of the gyroelongated pentagonal pyramid has 11 faces: 5 kites, 1 regular pentagonal and 5 irregular pentagons.

**How many edges does a 12 face prism have?**

How many faces, edges and vertices does a prism have?

Shape | Faces | Edges |
---|---|---|

Pentagonal Prism | 7 | 15 |

Hexagonal Prism | 8 | 18 |

Cube | 6 | 12 |

Cuboid | 6 | 12 |

#### What is the formula of the area of a pyramid?

The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.

**What is a 12 sided prism called?**

dodecagon

A dodecagon is a 12-sided polygon.

**How do you find the area of a prism?**

To find the surface area of a prism, use the formula SA=2B+ph, where SA stands for surface area, B stands for the area of the base of the prism, p stands for the perimeter of the base, and h stands for height of the prism.

## What is the area of prism?

The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where “S” is the surface area of the prism.

**What is a pyramid with 13 faces called?**

Dodecagonal Pyramid. Number of faces: 13.
