A, B, and C are three cubes of wood with different sizes, and the lengths of the sides of A are (1/3) and (1/4) of the lengths of the sides of B and C respectively. If three kinds of wood blocks A, B, and C are used to assemble a large cube with the smallest possible volume, and at least one piece of each kind of wood is required, how many pieces of these three kinds of wood are needed at least?
甲、乙、丙三种大小不同的正方体木块，其中甲的棱长分别是乙、丙的棱长的(1/3)、(1/4)．如果用甲、乙、丙三种木块拼成一个体积尽可能小的大正方体，要求每种木块至少用一块，那么最少需要这三种木块多少块？
