An adult African elephant can weigh up to 7 tons. At birth an African elephant weighs about 200 pounds. How many more pounds does an adult African elephant weigh than a newborn?

One tonne is equal to about 2,000lbs. So, if an adult African Elephant weighs 7 tonnes, that is about 14,000lbs. If you subtract 200lbs from 14,000, you get 13,800.

1 tonne = 2,000lbs

7 tonnes * 2,000lbs = 14,000lbs

14,000lbs - 200lbs = 13,800

So your answer would be an adult African Elephant is about 13,800lbs more than a new born elephant.
