Let's take any edge length l. The diagonal has length

. In our case it's
Answer:
6.64 seconds
Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled,
= 709 feet
Initial velocity of the bucket,
= 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
or 32.1741 
Let the time taken is
seconds.
Formula for distance is given as:

Putting all the values:

Answer:
it's either 32 or 16f I don't know though
