A cube of edge length 0.05m is positioned as shown in the figure below. A uniform magnetic field given by B = (5i+ 3j+ 2k) T exists throughout the region.

a) Calculate the flux through the shaded face.

2. Relevant equations

[itex]\phi[/itex] = B.A cos [itex]\theta[/itex]

3. The attempt at a solution

The area would simply be 0.0025m^2

I'm having trouble understanding how to get the angle and also how to interpret the given magnitude of the magnetic field, it's a vector quantity.

I thought at first the way to get the angle was to assume that the surface of the cube could be considered a vector as well, that way it would only have the j component since it's only got a direction in the y-axis.

Then using the formula for the angle between two vectors, I got 53.5 degrees, though I'm not too sure how to use the given magnetic field value.
