You find volume by one shape at a time, then add all the shapes together to find the sum of all the shapes..
Volume of a Square/Rectangle = Height x Width x Depth / 1728
Volume of a Right Triangle = Height x Depth x 1/2 of the base.
Add the two together and Wahlah. :)

yeah just break it into pieces, and find the area of each, not that hard. the design is very nice. let us know how it turns out.

No need to break it into pieces like these guys are saying. Right click on the floor of the enclosure and then select area -> selection. This will give you the area of the bottom of the enclosure. From there, multiply by the height and then divide by 12 if the height is in inches.
Just like in these pictures:
You may need to block off the area that is below the port as your port doesn't touch the bottom of the enclosure.

I never used SketchUp. I didn't know it was capable of such features. Neat though.
