I think you would need 25 slabs in total (if my quick sketch is accurate)
18 for the 9 x 2 main part, uncut slabs
5 need to be cut in half to create the 9 x 1/2 slabs, leaving one x 1/2 slab which you would need to cut again to make a slab 1/2 x 2/3.
Finally, you need 2 slabs cut to 2/3rds width. You would be left with 2 x 1/3rd pieces left over.
Don't take the "no waste" bit of the question to mean "no remainder" or "no bits left over".
It's implying that you don't make a mistake and cut a slab to the wrong size, or if cutting it the old-fashioned way (with a hammer and bolster), you don't get a slab cracking in totally the wrong place, so the whole slab is wasted as it can't be used.
If doing this in real life, yould probably buy a few slabs over what you require to allow for mistakes when cutting.
