Book 25, Question 4
How tall is the tallest building in the world?
The Burj Khalifa in Dubai is the tallest building in the world.
It is 2,717 feet tall, with 163 floors, about twice as tall as the Empire State Building in New York. It tapers as it rises, and from the top you can see for many miles. Engineers had to design it carefully for wind and for very hot weather.
