The world's tallest building is the Burj Khalifa in Dubai at 828 m tall.
The CN Tower in Toronto is 553 m tall.
Ryan wants to compare the Burj Khalifa and the CN Tower by creating rectangular prism models on a 10 cm by 10 cm square base. He has decided to represent the Burj Khalifa with a rectangular prism that has a height of 50 cm.
What is the height of the rectangular prism he should use to represent the CN tower?

h = (553m/828m) * 50cm = 33.4 cm.
