How to calculate the volume of a triangular prism

You may think that the volume of a triangular prism is calculated in the same way as that of a pyramid, but this is not at all the case. Indeed, a triangular prism is a polyhedron made up of two triangular bases and three rectangular lateral faces. To calculate its volume, you just need to determine the area of one of the triangular bases and multiply it by the height of the prism.

1- Calculate the area of a triangular base

Find the necessary dimensions. Find the width and height of the triangle. Look at it and note the length of its base as well as its height. Be sure to note the height of the triangle, not the prism.You can measure any of the triangular bases, because they have exactly the same dimensions.

Use the appropriate formula. Note the formula for calculating the area of a triangle. Once you have measured the dimensions of the triangular base, apply the formula with these measurements. The formula for calculating the area of a triangle is as follows :
A being the area of the triangle, b the length of its base and h its height. 
Do not forget to note the final result in square units, because it is the area of a polygon.

2- Calculate the volume of the triangular prism

Write the formula for calculating the volume of a prism by entering the area of the triangular base that you have already calculated. This is one of the two numbers you need to calculate the volume of the polyhedron. The formula to use is  V = A * h, V being the volume of the prism, h its height (The height of a prism is the length of one of its lateral edges between the two bases) and A the area of the triangular base

The result obtained corresponds to the volume of the polyhedron in cubic units

Advice
Make sure the base unit of measure is the same for all dimensions before performing the calculation. For example, if one measurement is given in millimeters and the others in centimeters, convert millimeters to centimeters or vice versa before calculating the volume of the prism.

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

Image
See the image of a triangular prism given below. It can be seen that it has two triangular faces and three rectangular faces. So How many faces, edges, and vertices does a triangular prism have?   A triangular prism has 5 faces. Both the triangles have three vertices each, which are not common. The vertices of the rectangles are covered when we consider the vertices of the triangles. A triangular prism has 6 vertices. Each vertex of a triangle is joined to a vertex of the other triangle by an edge. Each of the vertices of a particular triangle are joined to its two other vertices by an edge each. These edges include all the edges of the rectangles. A triangular prism has 9 edges.

Definition of Triangular Prism

What is a triangular prism in geometry? In geometry, a triangular prism or "three-sided prism" is a polyhedron made from a triangular base, a translated copy and 3 faces joining the corresponding sides. If the sides are squares, it is called a uniform polyhedron . Equivalently, it is a pentahedron whose two faces are parallel, while the normals to the surfaces of the other three are in the same plane (which is not necessarily parallel to the planes of the bases). These three faces are parallelograms. All cross sections parallel to the base faces are the same triangle. A right triangular prism is semi-regular if the faces of the bases are equilateral triangles, and the other three faces are squares. A general right triangular prism can have rectangular sides. The dual of a triangular prism is a 3-sided bipyramid. The symmetry group of a 3-sided straight prism with a regular base is the prismatic group D3h (en), isomorphic to the dihedral group D6 of order 1

Surface area of a triangular prism

The surface area of a right triangular prism is the area of the three rectangular sides plus the area of the two triangles forming the bases. s1, s2, s3 = lengths of the sides of a triangle b = base of the triangle (equal to one of these three lengths, as desired) h = height of the triangle associated with this base H = Height of the prism s1 + s2 + s3 = perimeter of the triangle How to calculate the volume of a triangular prism The Definition of Triangular Prism How many faces, edges, and vertices does a triangular prism have?
