Burj Khalifa is the world tallest building in Dubai at 828 m tall.
The CN Tower in Toronto is 553 m tall.
Sam wants to compare the Burj Khalifa and the CN Tower by creating rectangular prism models on a 10 cm by 10 cm square base. She 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?

553/828 = x/50
Solve for x.
