NUMBER & ALGEBRA – PLACE VALUE to 100 PHOTOGRAPHS – Floor numbers

« Go back

I love seeing numbers in real life. But it gets difficult to see quite large numbers doesn’t it. We have just included 4 new photographs of floor numbers in high rise buildings (Floor 27, 28, 29 and 80). The larger of these numbers is a little blurred but it is Floor 80 in the Empire State Building in New York.  It was taken by our gym buddy, Costa, on a recent trip to New York. Imagine all the class discussions that relate to floor levels. For example, the Empire State Building has 102 floors. But is this the most in the world? It is 381 m tall or 443 m from the ground to the tip at the very top. What does that tell us about the height of each floor? It was built way back in 1932 so imagine all the buildings that must be even taller than this today.

Currently the Burj Khalifa in Dubai is the world’s tallest skyscraper with a height of 828 m. It was built in 2010 and has 163 floors. The Empire State Building is now only the 34th tallest building in the world. But in 2020, the Jeddah Tower in Saudi Arabia will become the world’s tallest building. It will be 1008 m tall. That’s more than a kilometre!!!!! And it will have 167 floors at a crazy cost of about $1.5 billion. It was originally planned to be 1.6 km tall – that’s one mile in the old measures. It was designed by the architect Adrian Smith, who also designed the Burj Khalifa.
