Fiona chopped down an old tree and cut the trunk into 24-inch lengths. Because the tree had been dead for so long, there were no branches left. They had all fallen off.
Next, Fiona split each length into 4 pieces so that each piece was thinner and not so heavy, but still 24 inches long.
Now she had 80 logs to burn in her wood stove.
How many feet tall had the trunk of the tree been?I have been working on a math course over the last couple weeks.
