Hold on to your hats folks, we’re about to dive into the wild world of geometry! Ever wondered how to calculate the surface area of a triangular prism? No? Well, you’re going to learn anyway! Let’s get our maths on!

Table of Contents

## Formula

The formula to calculate the surface area of a triangular prism is as follows:

```
Surface Area = bh + (s1 + s2 + s3)l
```

Where `b`

is the area of the base, `h`

is the height of the triangle, `s1`

, `s2`

, and `s3`

are the sides of the triangle, and `l`

is the length of the prism.
