甲组代表带来了等底等高、等底不等高、等高不等底的三组圆锥和圆柱量筒以及足够的沙子。先将圆锥注满沙子 ,倒入圆柱中 ,观察几次倒满 ,发现等底等高正好三次 ,即圆柱的体积正好是圆锥的三倍。而等底不等高、等高不等底却不存在倍数关系 ,从而得出圆锥体积公式。乙组代表带来? A group of representatives brought the end of the contour, at the end of unequal height, contour does not end with the three sets of conical and cylindrical measuring cylinder and enough sand. First cone filled with sand, into the cylinder, observed several times full, found exactly the same contour exactly three times, that is, the volume of the cylinder is exactly three times the cone. But not so high at the end, contour does not end there is no multiple relationship, thus come to cone volume formula. B representatives bring?
