Hello!
Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.
343 · 5 = 1715 meters per 5 seconds.
1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.
1715 / 1000 = 1.715
Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.
The logarithmic model for the length when the strength is of 8 Pascals is given by:
- That is, the length is of 3 units.
<h3>What is the function?</h3>
The strength in Pascals for a building of length x is given by:
To find the length given the strength, we apply the inverse function, that is:
Hence, when the strength is of 8 Pascals, 
, and the length is given by:

A suitable calculator* can do this easily.
61°38'45" = (61 +(38 +45/60)/60)° ≈ 61.65°

I like the RealCalc app for Android, but many graphing calculators also will do this conversion. Of course, you can simply evaluate the expression as above.
Answer:
All the sides are equal. any number as long as all the sides have the same number.
