Having been to Paris, Rob 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 Khalid? My answer is (1887-324)=1563 m or 2390m tall.
Thanks
what does the year it was built have to do with its height?
I noticed it also. That is how the question was presented. I looked up Burj Khalifa is 2,717 - 324 = 2393.
To find out how much lower the Eiffel Tower is compared to the Burj Khalifa, we need to determine the height of the Burj Khalifa and then subtract the height of the Eiffel Tower from it.
The Burj Khalifa is currently the tallest man-made structure in the world. As of my knowledge update in May 2021, the height of the Burj Khalifa is approximately 828 meters or 2,722 feet.
To calculate the difference in height, we subtract the height of the Eiffel Tower (324 meters) from the height of the Burj Khalifa (828 meters):
828 meters - 324 meters = 504 meters
Therefore, the Eiffel Tower is about 504 meters lower than the Burj Khalifa.
Your calculation of (1887 - 324) = 1563 meters or 2390 meters tall appears to be incorrect. It seems like you subtracted the height of the Eiffel Tower from the year it was built. However, the height of the Eiffel Tower has no relation to the year it was built.
