Given the electric flux density, use D = 1/16(x^2yzx^ + xy^2zy^ + xyz^2z^) to determine the charge density (Δ́ጵ) and the total charge (Q) enclosed in a cube 2 m on a side, located in the first octant with three of its sides coincident with the X, Y, and Z axes and one of its corners at the origin. Calculate Q = ∫∫∫ρv dv.

Q3: Given the electric field D = x xy^3 z^3 (V/m) Find (a) The total volume charge density at a point (x,y,z)? (b) The total charge Q enclosed in a cube 1m on a side, located in the first octant with three of its sides coincident with the x, y, and z axes and one of its corners at the origin. Use the volume integral of the volume charge density found in part (a). (c) The total charge Q in the cube by applying GAUSS’ Law.
