reproduce the scale drawing so that it has a scale of 1 box = 2 centimeters. which shows the correct drawing the height is 2 boxes and the length is 6 boxes

To reproduce the scale drawing with a scale of 1 box = 2 centimeters, we need to double the dimensions of the original drawing.

Since the original height is 2 boxes and the original length is 6 boxes, the reproduced drawing will have a height of 4 centimeters and a length of 12 centimeters.

Here is the correct drawing:

```
------- ------- ------- ------- -------
| | | | | | | | | |

------- ------- ------- ------- -------
```

The height is represented by 4 vertical boxes and the length is represented by 12 horizontal boxes.
