A jeweler is setting a stone cut into the shape of a regular octahedron. A regular octahedron is a solid with eight equilateral triangles as faces. The formula for the volume of the stone is V = 0.47s³ where s is the side length in mm of an edge of the stone. The volume of the stone is 161 mm³ .

Find the length of an edge of the stone.
