The height SO of a regular quadrangular pyramid SABCD forms an angle 60o with a side edge , the volume of this pyramid is equal to 18 cm3 . The vertex of the second regular quadrangular pyramid is at point S, the center of the base is at point C, and one of the vertices of the base lies on the line SO. Find the volume of the common part of these pyramids. (The common part of the pyramids is the set of all such points in space that lie inside or on the surface of both pyramids). 3D geometrygeometryVolumepyramidChampions Tournament
