A cube with semicircular groves is shown below. To obtain its centroid, it is subdivided as follows: Part 1 is the entire cube without the groves; part 2 is the front grove whose center line is the z-axis; part 3 is the back grove. Determine the volume of part 1 in mm^3. 150 150 25 25 y 150 Answer: 50 25 Dimensions in millimeters 50 25
