Answer:

39 in or 3'3"

Step-by-step explanation:

(PLEASE ANSWER: TIMED)The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I(dB)=1

For this case we have the following equation:
$l(dB) = 10log( \frac{l}{lo} )$
We must replace the following value in the equation:
$l = 10^8lo$
Substituting we have:
$l(dB) = 10log( \frac{10^8lo}{lo} )$
Simplifying the given expression we have:
$l(dB) = 10log(10^8)$
Then, using logarithm properties in base 10, we can rewrite the expression:
$l(dB) = 10(8)$
Finally, making the product, the result is:
$l(dB) = 80$
Answer:
$l(dB) = 80$
