Answer:
144
Step-by-step explanation:
You find the volume of the cube using length*width*height (6*6*6) to be 216. Then, find the volume of the pyramid using (base*height)/3. Your base would be 6*6, which is the area of the flat square bottom, and your height would be 6, so it would be (((6*6)*6)/3), which is 72. You then subtract 72, your pyramid, from 216, your cube, and get your answer
