if pyramid is placed into tank then water is filled completely into the cubical tank, volume of water poured should be 27000-1000=26000cm3. When the pyramid is removed, minus off the vol of pyramid which you'll get 25000cm3. Then divide it by 30cmx30cm (lengthxheight), since volume of cubical tank= lengthxheightxdepth.
