Mass = 1066.52 gramsVolume = 135002.52 cubic millimetersSurface area = 18681.37 square millimetersProcedure: I started this model with the sketch from the front view. Started with the circle on the origin, then I sketched all the lines above and to the left of it. Then I created a centerline to the right with the right length, then I sketched out all the lines on that side of the model. Then, I created the two arc pieces on the bottom part of the model using a circle, the CenterPoint arc (based on the circle), and a sketch fillet. Finally, I created the arc on the top side of the model and extruded it out to the right dimension.
