# Prisms

Prisms are polyhedra that have two parallel, equally sized faces called bases and their lateral faces are parallelograms.

The height of a prism is the distance between the bases.

The lateral edges of a prism are equally sized parallel edges.

## Types of Prisms

### Regular Prisms

The bases of the regular prisms are regular polygons.

### Irregular Prisms

The bases of the irregular prisms are irregular polygons.

### Right Prisms

The lateral faces of the right prisms are rectangles or squares.

### Oblique Prisms

The lateral faces of the oblique prisms are rhomboids or rhombi.

### Parallelepipeds

The bases of parallelepiped prisms are parallelograms.

### Cuboid

The faces of cuboids are rectangular faces.

## Types of Prisms by Their Base

### Triangular Prism

The bases are triangles.

### Square Prism

The bases are squares.

### Pentagonal Prism

The bases are pentagons.

### Hexagonal Prism

The bases are hexagons.

### Volume of a Prism

#### Examples

Calculate the height of a prism whose base has an area of 12 dm² and whose capacity is 48 liters.

Calculate the lateral area, surface area and volume of a prism whose base is a rhombus with diagonals of 12 and 18 cm.
