Trapezoid Block

Material Cast Stainless Steel. TB1: Density = 0.01 grams per cubic millimeter Mass = 3194.77 grams Volume = 414905.39 cubic millimeters Surface area = 58496.82 square millimeters I created a square and then a on a new plane, below the first square, a smaller square. I extruded the larger square and then at the same time, angle it. Then, create a circle and cut extrude it. Finally just mirror it. TB2: Density = 0.01 grams per cubic millimeter Mass = 2195.20 grams Volume = 285090.77 cubic millimeters Surface area = 47106.81 square millimeters Create the TB1. Create a bigger circle on top of the other and cut extrude it but not all the way through on top and bottom face. Fillet the middle edges. Lastly create a square, covering 1/4 of the trapezoid block and cut extrude it. TB3: Density = 0.01 grams per cubic millimeter Mass = 2232.33 grams Volume = 289912.54 cubic millimeters Surface area = 54212.30 square millimeters Create TB2. Sketch edges on the top face only and extrude them. Using the slot command, sketch 4 slots on the corners of the top face only. Cut extrude the slots but not all the way.
