How to find the area of ​​a triangular prism

A prism is defined as a solid figure with a uniform cross section. There are many different types of prisms, from rectangular to circular to triangular. You can find the surface area of ​​any type of prism with a simple formula, and triangular prisms are no exception. It may be helpful to understand how to calculate the surface in this way if you are working on a project in the home that contains triangular prisms, or if you are simply trying to help your child with his math homework.

Steps to follow:

one

Determine the measurements of the base of the prism. You need to know the length of one side of the triangle and the height between that side and the opposite vertex. Find the area of ​​the base with the following formula: area of ​​the base = 1/2 --- side of the base --- height. Write down this value.

two

Measure the three sides of the triangular base and the height of the prism between its two bases. Write down these values.

3

Use the prism measurements to find the perimeter of the base with this formula: Side 1 + side 2 + side 3. Enter this value.

4

Calculate the surface of the triangular prism with this formula: (2 --- area of ​​the base) + (perimeter of the base --- height of the prism). Fill in the value for the area of ​​the base, which is in step 1, and the value for the perimeter of the base, which is in step 2. The resulting value of this final equation will give you the surface of the triangular prism .
