# Surface area of triangular prisms

## Formula to calculate the surface area of triangular prisms:

The surface area of a triangular prism is actually the total sum of the areas of the two bases of the prism (triangles), and the areas of the three lateral sides of the prism (rectangles).

To better understand, let's look at a simple example. In the following drawing, we have a right triangular prism:

The area of each base of the right triangular prism is $6$ cm².

The lateral sides of the prism have areas of $8$ cm, $10$ cm, $12$ cm.

The surface area of this prism can be calculated using these data as follows:

$S=6\times2+8+10+12=42$

So, the surface area of the prism is $42$ cm².
