Surprisingly, you don't need any extra information.
It was supposed to be a riddle.
"You dig a hole 5 meters wide and 10 meters deep. The circumference is 8 feet and the diameter is 4. How many cubic squares of dirt are in it?"
Since it's a HOLE there IS NO dirt in it, thus, having no cubic squares of any particular thing.
and BTW...I chose you as the winner(: (Since there was no othe better answer lol)
