A rectangle-based right pyramid

A B C D V

with a bottom edge length of

6

units and the perpendicular height of

6

units is placed in a coordinate system (see the picture). Let

S

be the midpoint of the edge

A D

. Find the standard equation of the plane

α

passing through the points

B

V

and

C

, and calculate the distance of the point

S

from

α

α : 2 y + z - 12 = 0; d = | S α | = \frac{12 \sqrt{5}}{5}

α : 2 x + z - 12 = 0; d = | S α | = \frac{12 \sqrt{5}}{5}

α : 2 y + z - 12 = 0; d = | S α | = \frac{6 \sqrt{5}}{5}

α : 2 x + z - 12 = 0; d = | S α | = \frac{6 \sqrt{5}}{5}
