For more on marking an answer as the "Best Answer", please visit our FAQ.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.
