The tree's girth turned out to be 140cms. Charlie divided that by 2.5 and estimated that the tree they had measured had been about 56 years old!
All the other bears had listened with interest about how to find out the age of a tree, even if it wasn't quite exact, and they all decided that they would like to try it out the next time they went to the woods.
"We could take a tape measure and do the workings out while we were there," suggested Charlie, "and if anyone didn't want to hug a tree - but who wouldn't? - then we could simply place the tape measure around the tree to measure the girth."
"We'd need to take a calculator, too" Bubbles proposed. "Not all of us can work sums out with just a piece of paper and a pencil like you Charlie." Everyone giggled - quite a few bears might need some help when it came to doing the sums!
The bears can't wait for their next trip into the woods. They were all eager to choose a tree and see who could find the oldest! Or the youngest! And to go back to the same tree the following year and see how much it had grown! Very exciting!
