+### How can I use a price per square meter (m2) or per block (m3)?
+You can set a price using the region variables and complete JavaScript expressions (result of the last statement is used):
+
+Charge $5 per square meter:
+```yaml
+price: '5*%width%*%depth%'
+```
+
+Charge $5 per block:
+```yaml
+price: '5*%width%*%depth%*%height%'
+```
+
+You can put this in `default.yml`, a group in `groups.yml` or in a region file. You cannot set a price like this using `/as setprice` for security reasons.
