Is there a way to get surfaces volumes from Dynamo?

With a Great help from Paolo I Manage to create this Python Scrypt to get the surface volume:

Find the attached Dynamo file, you’ll have to change the “VOL-PG-FILL” for the name of the volume surface you want to get data from.

If you don’t have the volume surface created and you want dynamo to do it, check this Paolo script:
