The magnetic flux through one face of a cube is +0.120 Wb.
(a) What must the total magnetic flux through the other five faces of the cube be?
(b) Why didn't you need to know the dimensions of the cube in order to answer part (a)?
(c) Suppose the magnetic flux is due to a permanent magnet like that shown in Fig. In a sketch, show where the cube in part (a) might be located relative to the magnet.
