You just need to solve a few equations to find the answer to this problem.
First, you need to convert the 54 feet to inches. Since there’s 12 inches in a foot, you must multiply 54 by 12 to get 648 inches.
After that, you can set up another equation using the 2.54 centimeters to 1 inch. Since each inch is 2.54 centimeters, you must multiply the 648 by 2.54 in order to get 1642.92 centimeters.
Hope this helped!
