    Distance from a point to the plane

    What is the distance from the point (1,2,4) to the plane 2x+y+z=12 ?

    I got     5√6 / 6
    Anybody agree?

    The distance from the point (x_0,y_0,z_0) to the plane ax+by+cz=d is given by \dfrac{|ax_0+by_0+cz_0-d|}{\sqrt{a^2+b^2+c^2}}. Plugging in the numbers for this problem, I get 4\sqrt6/6.
