20 0 2年世界杯足球赛所用的足球名叫飞火流星 ,在不充气时它是一个由 1 2个正五边形和2 0个正六边形围成的 32面体 ,不妨称它为飞火流星体 ,简称“飞体” (图1 ) .新编高中《数学》中有C6 0 分子的结构图 ,其形状应是一个很小的“飞体” .本文将用两种方法探求“飞体”体积的 The soccer ball used for the 2020 World Cup is called a flying fire meteor. When it is not inflated, it is a 32-faceted body consisting of 12 regular pentagons and 20 regular hexagons. Let’s call it a flying fire. The meteor body, referred to as “flying body” (Figure 1). The structure of the C6 0 molecule in the new high school “Mathematics” should be a small “flying body”. This article will use two methods to search for “flying.” Body "volume
