I need a simple sentence for Solid Intersection and Volume Moments

Hi
This is the my first topic.
I started VB for Grasshopper , two month ago.
I need a simple sentence for Solid Intersection and Volume Moments.

Dim result As Brep() = Brep.CreateBooleanIntersection(brepsA, brepsB, tolerance)

Dim vm As VolumeMassProperties = VolumeMassProperties.Compute(brep)
Dim centroid As Point3d = vm.Centroid

Dear David Rutten

Thank you very much.
Yesterday, I tried the VB programing about 4 hours.
But I could not fixed.

And I thought that I must more study and do try_and_error.
I think that I must read the documents about the Grasshopper and VB.
I will try hard !!
