Hope Primary School has a cuboid classroom with a length of 10 meters, a width of 6 meters and a height of 3.5 meters. If tiles with a height of 1.2 meters are pasted on the four walls of the classroom, and the area occupied by doors, windows, and blackboards is 6 square meters, what is the area of tiles on the four walls of this classroom?
希望小学有一间长10米、宽6米、高3.5米的长方体教室．如果在教室四面墙壁贴1.2米高的瓷砖，其中扣除门、窗、黑板所占面积6平方米，这间教室四面墙壁贴瓷砖的面积是多少平方米？
