Calculate the sound level in decibels of a sound wave that has an intensity of 2.25 µW/m2

For this question don't I use B=log10(I/IO)
So it would be B=log10(2.25/1.0e-12) right?

    2.25 microwatts is a millionth of a watt, or 2.25x10^-6 W/m^2. This is divided by 1e-12, so the solution is:
    B=10log10(2.25e+6)
