OK

pu2. I think the island is in volume
There are only polished rice, but rice has a skin, so it would be lighter if it was the same size

OK

pu3. Rice 1 Island: Approximately 180 L (liter) = 144 kg
Rice 1 Island: Approximately 200 kg (approximately 144 kg when polished) = Approximately 10 horses
So the conclusion is that rice is heavier than rice
