5. An Exceptional Weight
If you think the height is something to behold, you should also take a look at the weight. Naturally, a lot of materials were used to create something so big. Large amounts of aluminum were put into the creation of the Burj Khalifa, with the total amount weighing as much as 5 A380 aircrafts. There were also 55,000-ton steel rebar and 110,00-ton concrete used to complete construction on the massive building. To put this into perspective, the amount of concrete used weighs as much as 100,000 elephants. Plus, if you laid the rebar down from one end to another, it would stretch to one-quarter of the way across the Earth.
