There are two storage pools, A and B. Originally, the amount of water stored in pool B is less than that of pool A (1/6). Now, after injecting 1/5 of the water stored in pool A into pool B, 28 cubic meters are drawn from pool B. meters of water. At this time, the volume of water in the two pools is exactly the same. How many cubic meters of water is there in pool A?
甲乙两个蓄水池，原来乙池存水数量比甲池少(1/6)，现在把甲池中存水的(1/5)注入乙池后，再从乙池中抽走28立方米的水，这时两个池中的水量恰好同样多，甲池原来有水多少立方米．
