Given a vector field $$\overrightarrow F ,$$ the divergence theorem states that

$$\oint {\overrightarrow F .d\overrightarrow s = \int\limits_v {\Delta \,\,.\,\,\overrightarrow F \,dv} } $$

$$\int\limits_s {\overrightarrow F .\,\,d} \overrightarrow s = \int\limits_v {\Delta \times \overrightarrow F \,\,dV} $$

$$\int\limits_s {\overrightarrow F \times \,d} \overrightarrow s = \int\limits_v {\Delta \,\,.\,\,\overrightarrow F \,\,dV} $$

$$\int\limits_s {\overrightarrow F \times \,d} \overrightarrow s = \int\limits_v {\Delta \,\, \times \overrightarrow F \,\,dV} $$
