Well, the number of stories for 20 meters varies. If we assume each story is about 3.5 meters high, then it could be roughly 5 to 6 stories. However, building heights can differ based on design and purpose.
It's difficult to say exactly as the height of each story can vary. But typically, each story in a building is around 3 to 4 meters. So, 40 meters might be around 10 to 13 stories.
