What kind of figure? If all else fails, drop it in a liquid and see how much liquid is displaced.

hmmm.. im not really sure in the figure. but my classmate said it is an irregular figure drawn on the board, like cylinder with a pyramid on the top and a square on the left.(the three figure is connected with each other.) haha! confusing on how to come up with the answer.

Well, I'm not exactly sure how the figures are connected, but the volume of a cube is: where s is the length of a side, the volume of a cylinder is: , where r is the radius and h is the height, and the volume of a pyramid is: where b is the area of the base, and h is the height. I would need the details of how they figures are connected to compute the volume.
