The electric flow is defined as the change of the charge in relation to the constant of the vacuum permittivity constant.
That is to say that mathematically this expression could be given as
[tex]\Phi = \frac{q}{\epsilon_0}[/tex]
Here,
[tex]\Phi[/tex] = Electric Flux
q = Charge
[tex]\epsilon_0[/tex] = Vacuum Permittivity
Replacing with our values and solving to find q, we have,
[tex]-1850N\cdot m^2/C = \frac{q}{8.854*10^{-12} C\cdot N^{-1} \cdot m^{-2}}[/tex]
[tex]q = - 1.63799*10^{-8}C[/tex]
Therefore the charge is enclose within the octahedron with a charge of [tex]- 1.63799*10^{-8}C[/tex]
