Welcome to the wild and whimsical world of cuboid surface area calculations! This is not your typical math class. We’re stepping into the realm of cuboids where every side counts twice!

To calculate the surface area of a cuboid, we use the following formula:

```
2lw + 2lh + 2wh
```

where l is the length, w is the width, and h is the height.
