The Burj Khalifa, found in Dubai, United Arab Emirates, is known as the tallest building in the world, with a total height of 829.8m (2,722 ft). It’s three times as tall as the Eiffel Tower and nearly twice as tall as the Empire State Building. Everything about the tallest building, Burj Khalifa is superlative and involves extravagant numbers.
For example, it would take 36 workers about three months to clean the entire structure from the top to the bottom of the building.
One of the most mind blowing Burj Khalifa facts is how much the materials weigh. To put things into perspective, the weight of the concrete is equivalent to 100,000 elephants, while the total weight of aluminum used on the tallest structure is also equivalent to five A380 aircraft, which is the world’s largest passenger airliner.
