How Cao Chong Had the Elephant Weighed Cao Cao was very glad to have received an elephant as a present. He wanted to know how heavy the elephant was, but there was no scale(秤) big enough to weigh such a huge creature. One day, Cao Chong said to his father.“I’ve found a way to weigh the elephant .” Cao Chong asked a man to lead the elephant onto a boat.When the boat stopped sinking ，the man draw a line along on the boat side. After the elephant was led away, Cao Chong had some men put stones into the boat until the water reached the line. Cao Chong asked the men to weigh each stone from the boat and put down the number. “Add up all the numbers and we will know the weight of the elephant.”Cao Chong said to his father with kind of pride.
