Find the number of decibels for the power of the sound given. Round to the nearest decibel.
A rocket engine,
2.68 cross product 10−5
watts/cm2

2.68*10^5 watts/cm^2 to dB
You want Watts/m^2
so multiply by 10^4
2.68 * 10^1 Watts/m^2
definition of dB for sound:
dB = 10 log (watts/m^2 intensity /10^12)
= 10 log (2.68*10^11)
=10 [ log 2.68 + 11 ]
= 10 [ 11.428 ] = 114 dB LOUD !!!!
