    estimate divF

    A vector field  \vec{F} has the property that the flux of  \vec{F} out of a small cube of side 0.01 centered around the point (2, 9, 11) is 0.003. Estimate div  \vec{F} at the point (2, 9, 11).

    Can someone help me how to start this problem off?

    Flux = volume integral of divergence

    if the cube is small divF is approx constant

    Flux = divF*Volume

    ok so :

    divF = flux/volume...

    = 0.003/(0.01)^3

    = 3000

    hope this is this correct
