having been to Paris,Rob also remembered the Eiffel tower which was the tallest structure in the world at the time it was built in 1887.if the Eiffel tower is 324m tall,how much lower is it compared to today's tallest man-made structure, the Burj Khalifa ?

To find out how much lower the Eiffel Tower is compared to the Burj Khalifa, we need to know the height of the Burj Khalifa. Let's try to find this information.

Step 1: Open a search engine like Google or Bing.

Step 2: Type "height of the Burj Khalifa" in the search bar.

Step 3: Look for a reliable source that provides the height of the Burj Khalifa. Typically, Wikipedia or official websites would have this information.

After performing these steps, we can find that the height of the Burj Khalifa is approximately 828 meters.

Now that we have the heights of both structures, we can calculate the difference.

Height of Eiffel Tower: 324 meters
Height of Burj Khalifa: 828 meters

To find the difference, we subtract the height of the Eiffel Tower from the height of the Burj Khalifa:

Difference = Height of Burj Khalifa - Height of Eiffel Tower
Difference = 828 - 324
Difference = 504 meters

Therefore, the Burj Khalifa is approximately 504 meters taller than the Eiffel Tower.
