Mass = 2232.33 gramsVolume = 289912.60 cubic millimetersSurface area = 54212.30 square millimetersMaking this model I first sketched on the top plane and extruded it down and up at angles going out, then cut extruded the circle in the middle of the model to make trapezoid block 1. then I selected the top of the model and cut extruded one of the corners off of it then on the top and bottom of the model I cut extruded a bigger circle but didn't go through the entire model to make trapezoid block 2. Then I made another sketch on the top of the model converted it and offset it in, then extruded it to make the wall on the top of the model. after that I cut extruded the slots on the top of the model to finish trapezoid block 3.
