It is hoped that at the opening ceremony of the school sports meeting, 16 square teams of 8*8 will enter the arena in sequence. If the distance between the square teams is 2 meters, and the distance between two adjacent rows in the square team is 0.5 meters, then the entire team How many meters long.
希望学校运动会开幕式上，16个8*8的方队顺次入场，若方队与方队之间的距离是2米，方队中相邻两排的距离是0.5米，则整个队伍长多少米．
