This illustrates how the material_id is used.
## Control the size of the applet
There are two places where the size of the applet can be defined:
Within the block, adding values to the GeoGebra parameters width and height will define the section of the applet that is to be shown.
Within the block's header, adding values to the iframe parameters width and height will enlarge or reduce the size of the applet, or even distort it.
```
[[geogebra height="100px" width="175px"]]
params["material_id"]="seehz3km";
params["height"]=200;
params["width"]=350;
[[/geogebra]]
```
In the block's head, `width="80%" aspect-ratio="2/3"` could be used instead to define relative sizes and possible distortions if needed.
If no size is defined the default is to have `width="500px" height="400px"` and these are also the dimensions used if values are missing and no aspect-ratio has been defined.
## Using the sub-tags "set", "watch" and "remember"
The "set", "watch" and "remember" tags to the `[[geogebra]]` question block link Maxima values to GeoGebra objects in various ways.
