What is the definition of prism?


What does a prism look like? A prism is a three-dimensional shape in our daily life. A prism has two types of faces. The prism is named according to the shape of its base.

The faces of a prism other than the top and bottom are called the sides of the prism. All sides are also the same, which we call a parallelogram. This means that the sides can be parallelograms, rectangles or even squares since their opposite sides are all parallel to each other. One of the most common examples of prisms is the cuboid. It has a rectangular base and is called a rectangular prism. In this article, we will also introduce the calculation method of this rectangle (right-angled prism).

Elements of prism

Prisms can be labeled with their characteristics, which helps characterize them.

Edge: The straight line connecting any two adjacent vertices of a prism is called an edge.

Vertex: The angle where any two sides of a prism meet is called the vertex.

Face: It is a closed flat surface bounded by vertices and edges.

Cross section of prism

The cross-section of a prism is the shape obtained when a plane intersects the prism along its axis. Based on the shape of the base, prisms can be divided into the following categories:

Triangular prism: The base of a prism is triangular.

Hexagonal prism: A prism with a hexagonal base.

Square prism: A prism with a square base. You may have seen a four-sided prism under a different name, it is also called a cube.

Pentagonal prism: The base of a prism is shaped like a pentagon.

Rectangular prism: A prism with a rectangular base. A cuboid is also called a cuboid.

How to find the volume of a cuboid?

Generally speaking, the volume of a cuboid can be calculated using the following formula:

Volume = length × width × height

Here’s how to find the volume of a cuboid step by step:

Determine the length (l), width (w), and height (h) of the cuboid. Make sure these measurements are in the same units (e.g. centimeters, inches, etc.).

Multiply the length by the width. This will give you the area of the base of the rectangular prism.

Base area = length × width

Multiply the base area by the height. This will give you the volume of the cuboid.

Volume = Base Area × Height

Alternatively, you can directly multiply the length, width, and height to find the volume:

Volume = length × width × height

Be sure to include the unit of measurement in your final answer. For example, if the unit of measurement is centimeters, the volume would be expressed in cubic centimeters (cm³).

Our factory focuses on the production of prisms and related products. If you are interested in our products and want to know more information, you are more than welcome to contact us!

Our factory is dedicated to manufacturing high-quality prisms, an optical component with a variety of applications and functions. Prisms are widely used in optics, physics, astronomy, photography and other fields.

A prism is a polyhedron that usually consists of two parallel polygons (usually triangles) and a rectangular face between them. They can break light into different colors or change the direction of light by refracting and reflecting it.

In addition to our standard prism products, we also offer customized solutions to meet our customers’ specific needs. Our team has extensive experience and expertise in working with customers to provide technical support and custom designs.
