A triangular prism is a 5 faced solid. Two of its faces are triangular, and these two faces are also called the bases to this shape. The rest of the three faces are rectangular in shape.
There are three principal stages to study about a triangular prism and they are given below;
1. The basic geometric terminology
2. Surface area and
3. The volume.
In this post we will explore all these aspects of a triangular prism one by one.
The key terms about a triangular prism are the first to speak about:
Kids can start to learn about the basic geometric shapes as soon as they are in grade one as a part to explore their spacial sense. The higher primary grades give a stage to learn all about the basic terminology of a triangular prism.
Edge of a triangular prism: An edge is the meeting line of two faces and there are 9 edges of a triangular prism.
Vertices: A vertex is defined as the meeting point of three edges and three faces. There are 6 vertices per triangular prism.
Prism Net: Kids in grade 5 or six are introduced with the net of a triangular prism and which is all the faces of the prism spread on the floor by cutting it by the edges.
How to find the surface area of a triangular prism:
If area of all the five faces of a prism is measured and then added together, what we get is called the surface area of the prism. Kids ought to know the formula to get the area of a rectangle and a triangle.
This is all they need, area of two triangles and three rectanges and add them to obtain the surface area of the prism. If students know, how to draw the net of a triangular prism along with the given units in the problem, they can do the task of finding surface area very easily.
Finding Volume Of A Triangular Prism:
The last but not least step to learn about a triangular prism is to know how to find its volume. As you already know that volume is the capacity to hold any material.
Grades eight or nine students are asked many questions about the volume of a triangular prism. The product of area of one of the triangular base and the height of the prism generate the volume. Thus, the volume of a trianular prism can be obtained by multiplying the area of a triangular base with the distance between both of the triangular faces of the prism.
In other words, the volume of the triangular prism is equal to the Area of Base times The height of the prism, where height of prism is the distance between it two triangular faces.
As a final world, it can be said that if students recognize basic terminology of a triangular prism along with idea to determine its surface area and volume, they can do all the math problems realted to this key geometric shape.
