For a pyramid S.ABC of volume V. Let M be a point on side AB such that AM/AB = x. The plane (alpha) through M is parallel to two
straight lines SA, BC. the plane (alpha) divides the pyramid into 2 parts, in which the part containing the point B has a volume of V' with V' = 208/343V. The sum of the values of x satisfies the problem. A. 3/2 B.3/7 C.135/686 D.0
