1. 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?

2. 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
