This will display the volume of each Solidbody in a part document:

Sub Main
	If ThisApplication.ActiveDocumentType <> kPartDocumentObject Then MessageBox.Show("This rule is designed to only work in part documents.", "Wrong Document Type") : Exit Sub
	Dim pDef As PartComponentDefinition = ThisApplication.ActiveDocument.ComponentDefinition
	
	If pDef.SurfaceBodies.Count < 1 Then MessageBox.Show("No Solids Exist", "Termination") : Exit Sub

	For Each sb As SurfaceBody In pDef.SurfaceBodies
		MessageBox.Show("Internal Calculation [cm^3]: " & Round(sb.Volume(0.0001), 5) & vbCrLf & _
						"Converted Calculation [in^3]: " & Round((sb.Volume(0.0001)/(2.54^3)), 5)	, "Volume for " & sb.Name & ":")
	Next
	
End Sub

Let me know if you have any questions.

Thank for you help, i see you use the below code to get the volume, so when is the Round method you use, I use C# so do you have a sample code in C# 

Round(sb.Volume(0.0001), 5)

 Thank and wait for your reply

I'm not familiar enough with C# to tell you how to round a variable, but Round(###, 5) rounds a number to 5 decimal places.   You can take Round(..., 5) out and just use:

sb.Volume(0.0001)

It will just have roughly 10 decimal places, but I'm not sure if that will let you use it in C#
