Trapezoid Block

The trapezoid Block how I built it was first created at rectangle dimensioned it to 96mm the I extruded it to 44mm after to create the end I extended then I added another block extruded to 44mm and after did the same thing to the top after created a circle dimensioned it to 50mm after extrude cut it then I create a sketched on the top then created a rectangle and it was already dimensioned it to 48mm then created a circle at 70mm diameter extrude cut both too 10mm after I did the same to the bottom then I I went back to the top and then after I did a sketch on the top offset the lines on the top then I closed the two end extrude it up after create a slot then dimensioned it and extrude cut it too 10mm Trapezoid block 3 Mass = 2232.33 grams Volume = 289912.60 cubic millimeters Surface area = 54212.30 square millimeters Trapezoid 2 Mass = 2195.20 grams Volume = 285090.83 cubic millimeters Surface area = 47106.81 square millimeters Trapezoid 1 Mass = 3194.77 grams Volume = 414905.39 cubic millimeters Surface area = 58496.82 square millimeters
