Hi my geometry question is- A new part needs to be designed for a machine. The cube center of the part has a side length of 2 in. Each cylinder off the sides of the cube has a diameter and height that matches the sides of the cube with a 1 inch hole drilled out 1 inch deep. There are 4 cylinders. How much metal is needed to make one part?

By graphing the boundaries of a 2d figure on a graph using these inequalities{3x-2y>-12,y<3,y>-3, and x<0, what is the volume and surface area of the 3d shape produced by revolving this 2d shape around the y axis?
