In January 2010, the Burj Khalifa Tower officially became the tallest building in the world. This tower has a curtain wall (the exterior skin of the building) that is approximately 133,500 square yards. Convert this to square feet.
1 square yard = 9 square feet
Multiply area by 9.
To convert square yards to square feet, you need to know the conversion factor between the two units.
One yard is equal to three feet. Therefore, one square yard is equal to 3 feet x 3 feet, which is 9 square feet.
Given that the curtain wall of the Burj Khalifa Tower is approximately 133,500 square yards, you can calculate the equivalent in square feet by multiplying 133,500 by 9.
So, 133,500 square yards x 9 square feet = 1,201,500 square feet.
Therefore, the curtain wall of the Burj Khalifa Tower is approximately 1,201,500 square feet.
