A prism is a solid figure with flat faces, two the same bases, and also an equal cross-section all along its length. The name of a details prism counts on the 2 bases the the prism which can be triangles, rectangles, or any kind of polygon. Because that example, a prism through triangular bases is called a triangular prism and a prism v a square basic is dubbed a square prism, and so on. A triangular prism has two triangle bases and also three rectangular faces. Let united state learn much more about the triangle prism in this article.

What is a triangular Prism?

A triangle prism is a 3D form with 2 identical deals with in the form of a triangle linked by three rectangular faces. The rectangular faces are described as the lateral faces, while the triangular faces are dubbed bases. The bases are likewise called the top and the bottom (faces) that the prism, respectively.

Triangular Prism Meaning

A triangular prism is a 3D polyhedron v three rectangular faces and two triangular faces. The 2 triangular encounters are congruent to every other, and the 3 lateral faces which are in the shape of rectangles are also congruent to each other. Thus, a triangular prism has actually 5 faces, 9 edges, and also 6 vertices. Observe the following figure to check out a triangle prism in which L represents the length of the prism, h to represent the height of the basic triangle, and b to represent the bottom sheet of the base triangle.


Triangular Prism Properties

The properties of a triangular prism aid us to determine it easily. Noted below room a couple of properties the a triangle prism:

A triangular prism has 5 faces, 9 edges, and 6 vertices.It is a polyhedron v 3 rectangle-shaped faces and 2 triangular faces.The 2 triangular bases are congruent to every other.Any cross-section of a triangular prism is in the form of a triangle.

Triangular Prism Net

The network of a triangular prism is a pattern that is seen as soon as the surface of the prism is opened, flattened, and also laid the end such that all the encounters are checked out clearly. This net have the right to be folded up to make a triangular prism. It shows that the bases the the prism room shaped in a triangle and also the lateral encounters are shaped favor a rectangle. The number given below shows the network of a triangular prism wherein the triangles and also the rectangles are seen clearly.


Surface Area the a triangle Prism

The surface ar area of a triangular prism is the area the is lived in by that surface. That is the sum of the areas of all the faces of the prism. Hence, the formula to calculate the surface ar area is:

Surface area = (Perimeter of the base × Length) + (2 × base Area) = (S1 +S2 + S3)L + bh


b is the bottom edge of the basic triangle,h is the elevation of the base triangle,L is the size of the prism andS1, S2, and S3 room the 3 edges (sides) of the basic triangle(bh) is the merged area of the 2 triangular faces, since <2 × (1/2 × bh)> = bh

For an ext information ~ above the surface ar area formula and calculations, inspect the write-up on the surface area of a triangle prism.

Volume of a triangular Prism

The volume the a triangular prism is the product that its triangular base area and also the length of the prism. As we currently know the the triangle prism basic is in the shape of a triangle, the area of the base will be the exact same as the of a triangle. Hence, the Volume that a triangular Prism = area of base triangle × length or the can likewise be created as Volume of triangular Prism = ½ × b × h × l, where b is the base length of the triangle, h is the elevation of the triangle, and l is the length of the prism.

Right triangle Prism

A right triangular prism is a prism in i m sorry the triangular encounters are perpendicular to the three rectangle-shaped faces. In other words, both the triangles of a ideal triangular prism space right-angled, therefore, the triangular faces are perpendicular to the lateral rectangular faces. A ideal triangular prism has 6 vertices, 9 edges, and also 5 faces.

Listed listed below are a few interesting topics the are pertained to the triangular prism.

Example 1: uncover the volume the a triangle prism that has actually the adhering to dimensions: base length of the triangle= 5 inches, height of the triangle = 3 inches, and also length of the prism = 8 inches.

Solution: Given, base size 'b' = 5 inches, the elevation 'h' = 3 inches, and length between the triangular bases 'l' = 8 inches.

Volume that a triangle Prism = ½ × b × h × l

Volume = ½ × 5 × 3 × 8

Volume = 60 in3

Therefore, the volume that the triangular prism is 60 inches3.

Example 2: What is the surface ar area of the triangular prism if its basic area is 12 square units, size is 15 units, and also the perimeter of the base is 21 units?


Given, basic area = 12 square units, size = 15 units, and also perimeter of the basic = 21 units. Therefore, the surface ar area the the triangle prism deserve to be calculated by applying the formula:
