A FreeCAD user created a user-friendly "Info" module which you can get here: http://www.sloan-home.co.uk/FreeCAD/Info/Info.html

If you're on Linux, you need to create a folder named "Mod" in the .FreeCAD hidden folder which is located in your Home folder. Then create a folder named "Info" in the "Mod" folder, and extract the content of the archive in it. On Windows, I have no idea where that would be. I guess it may be in C:\Program Files\FreeCAD\Mod.

Then start FreeCAD, open your STEP file and switch to the "Info" workbench with the workbench switcher or by going to the View --> Workbench menu. Now select your solid, and click on the "Info" icon; the left taskbar will show some information on the model, including volume, surface area, center of mass and moment of intertia.
