**1. The problem statement, all variables and given/known data**

"A continous sound wave with a sound intensity level of 80dB passes through a hole in a wall which has a cross-sectional area of 3m^2. How much energy passes through this hole in 10 minutes, in joules?"

If anyone can show me how this problem is solved it’s be much appreciated. Thanks

**2. Relevant equations**

dB = 10log10 (I/Io)

**3. The attempt at a solution**
