The best thing to do for this problem is to split the entire gasp into separate parts. It's easiest to draw the separate shapes out. I'll provide a picture for you, showing what I mean.
If you follow along with the image provided it should explain everything!
It's always nice to do things visually, it really helps to have more accuracy! Trust me! I'm not a mental math kind of girl.
(Your volume will be 406.)
Volume of entire shape= 406 cm^3
Now this should be the answer!
Hope this helps. If you have any questions let me know! :)
