正方体是立体几何解题中的重要背景图形.以正方体为模型突出考查空间想像能力的立体几何试题,一直是高考命题的热点,且创新试题不断.下面将近几年出现的有关正方体“计数型”应用题分类例析,以期对同学们有所帮助.
The cube is an important background image in solving a three-dimensional geometric problem. The three-dimensional geometry test that uses the cube as a model to highlight the spatial imagination ability has always been the hot spot of the college entrance examination proposition, and the innovative test questions are constantly. The following has been related to the cube “counting” "Application problem classification example analysis, in order to help the students.
