124 cubic cm...
What you have to do is, imagine you can cut it into two rectangular solids. The volume of a rectangular solid is:
(length times width times height.)
So, find the volume of each of the two pieces, and add those up.
So, assuming there are no hidden cut away areas hidden on the back side, it looks like you can cut this into:
one rectangular solid of dimensions 5 by 4 by 3
a rectangular solid of dimensions 2 by 8 by 4.
First one's volume is
second one's volume is
For a total of 124 cubic cm.
