There are several bamboo poles of different lengths inserted in the playground. After measuring, Xiaojun calculates that the ratio of the length of these bamboo poles to the corresponding shadow length is (2/3). At the same time, he also measures that the shadow length of the flagpole is 6 What is the actual height of the flagpole in meters?
操场上插有几根长短不同的竹竿，小军经过测量，计算出这几根竹竿的长和相应的影长的比值为(2/3)，同时，他还测得旗杆的影长是6米，则旗杆实际高度是多少米．
