三国时,曹操的一个朋友送给他一头大象。曹操很想知道这头大象的重量,可是由于大象体积太大,根本无法直接进行称重,众大臣们冥思苦想仍不得法。这时,曹操的儿子——聪明的曹冲想到了一个方法——把大象的重量转化为石头的重量,再通过石头的重量得出大象的重量。因此,他让人先把大象牵到船上,接着在船上刻下水位线;然后从船上牵下大象,把石头一块块装上船,直到水位线与大象在船上时的水位线相同;最后卸下石块,称出石头的重量,由此间接测出大象的重量。
When the Three Kingdoms, a friend of Cao Cao gave him an elephant. Cao Cao would like to know the weight of the elephant, but because of the size of the elephant is too large, can not directly be weighed, Ministers meditations still not law. At this moment, Cao Cao’s son, smart Cao Chong, came up with the idea of converting the weight of an elephant to the weight of a stone, and then the weight of the elephant through the weight of the stone. Therefore, he first brought the elephant to the boat and then carved the water line on the boat. Then he took the elephant from the boat and put the pieces on the boat until the water level was the same as that of the elephant on board. Finally, remove the stones, weigh the stone, which indirectly measure the weight of the elephant.
