132. Find the volume of the body obtained by rotating an equilateral triangle with side $a$ around a line parallel to its plane and such that the projection of this line onto the plane of the triangle contains some height of the triangle.
132. It is easy to see that the cross-section of the given body by a plane perpendicular to the axis of rotation is a ring, the area of which does not depend on the distance from the axis of rotation to the plane of the triangle.
