A ready solution to the problem. The sorcerer of Arutyunov. Task number 408.

401 - 410. Given a vector field F = Xi + Yj + Zk and the plane Ax + By + Cz + D = 0 (p), which together with the coordinate planes forms a pyramid V. Let σ be the base of the pyramid belonging to the plane (p); Λ is the contour bounding σ; N is the normal to σ, directed outside the pyramid V. It is required to calculate:
1) the flux of the vector field F through the surface σ in the direction of the normal n;
2) the circulation of a vector field F along a closed contour λ directly and applying the Stokes theorem to the contour λ and the bounded surface σ with the normal n;
3) the flux of the vector field F through the complete surface of the pyramid V in the direction of the outer normal to its surface directly and applying Ostrogradsky´s theorem. Draw a drawing.

408. F = (3x + 4y + 2z) j; X + y + 2z - 4 = 0
