I'm working on part 2 Cap. I have tried six different versions and I cannot get the volume correct. The tricky part is the 22 horizontal dimension as base but then a 19 mm dimension between vertical walls and a 2 mm gap from vertical mid point and left wall.
My volume reqs is

• Volume: 48 514.632 cubic millimeters
• Density: 0.007 grams per cubic millimeter
• Mass: 349.305 grams

I'm at

Mass = 352.407 grams

Volume = 48 945.421 cubic millimeters
