text: I then reasoned, that since the two planes are perpendicular to each other, the Octahedron is essentially a three-dimensional rhombus, and thus the volume of the Octahedron is actually the sum of 2 congruent "pyramids" (congruent, since the diagonals of a rhombus bisect each other, and are perpendicular to each other).
