How to get the volume of a solid in Sketchup Free Web Version

I cannot find the volume of a solid in Sketchup Free Web. I made a very simple solid component. it is not leaky. Anyone know how to get the volume? Its not in the entity info.

It’s apparently not implemented yet.

i want the old sketchup.

OK. You can still use SketchUp Make 2017 or SketchUp Pro.
