You are given a metallic solid sphere of radius R. You are required to recast the solid into smaller solid spheres to increase the total surface area as much as possible . The number of final products is unlimited . Suggest what you would do . (Hint: Recasting the solid into two smaller spheres of equal radii gives a 26% increase in its total surface area .)
你有你要重鑄固體進入比較小的堅硬球體增加總計的表面區域為很多如可能的一個半徑 R. 的金屬堅硬球體。 最後產品的數字是無限制的。 建議你將會做的。 (暗示: 重鑄固體進入相等半徑的二個較小的球體之內給 26% 它的總計表面的區域增加。)
