# Volume of a Triangular Prism Volume =
Height t × Base t/2
× Length

## Volume calculator for a triangular prism

Enter the length of the prism (length) and the height (height t) and base (base t) of the triangle that forms one of the bases of the prism to get the volume automatically.

If you know the area of the base (area base) you can enter this number along the length of the prism to get the volume automatically.

## Description, how many faces, edges and vertices are there in a triangular prism

The triangular prism, is a solid that, if we make a cross section, maintains the shape of a triangle throughout its length.

It has 5 faces, 2 faces are at the ends of the shape and both are considered bases; the two identical bases are parallel and identical triangles. In case these bases are not exactly aligned then we are in the presence of an oblique prism, and if the bases are not parallel then it is not a prism. It has 9 edges and 6 vertices.

## Examples of a triangular prism

We can find many objects that look like a triangular prism, examples of triangular prism shaped objects are: Inside of a kaleidoscope, that's right, most kaleidoscopes have a triangular prism inside, made of mirrors that make the image multiply itself to a hexagon. Another interesting place we can find this shape is on the cover of the album Dark side of the Moon by Pink Floyd.

## Formula for the volume of a triangular prism

To calculate the volume of a triangular prism you can use the formula for all prisms, where the area of the base is multiplied by its length. In this case the base of the triangular prism is a triangle, therefore you need to calculate the area of the triangle. You can also use the online calculator to calculate the volume of a triangular prism automatically.

Volume =
Height t × Base t/2
× Length

Formula explanation:
• The formula to calculate the volume for prisms is always the same:

Volume prism = Area base × Length
• In this case, the area of the base of the prism is the area of a triangle:

Area base = Area triangle = (base × height)/2
