A picture would be helpful, but I think the answer might be (6x4x3)+(3x4x4). If your shape is made up of many parts, you should find the volume of each shape then add them up to find the total volume. (To find volume, multiply base x height x width) If you could give a picture, it would be very helpful because I don't really know which numbers I should multiply to find volume. I hope this explanation helps, and please comment if you need to ask me anything.
