How many Blue Whales would it take to get to top of the 7 tallest buildings in the world?

A Blue Whale in length is 98 ft, so if you put it against the 7 buildings sideways it would probably take many whales as much as 25 or even 30!

It would take 27 adult Blue Whales on their side to match up to the size of Burj Khalifa the #1 tallest building in the world.For the 2nd which is the Shanghai Tower it would take 21 adult Blue Whales on their side to be the height of the Shanghai Tower.For the 3rd which is the Makkah Clock Tower Hotel in Saudi Arabia it takes 20 adult Blue Whales on their side to be as tall as the Makkah Royal Clock Tower Hotel.For the 4th tallest building in the world which is the One World Trade Center it would take 18 adult Blue Whales on their side to match the height of the Trade Center.
