Land Size
If you take a square mile and divide it into quarters, and then divide one of these quarters into quarters, and then, one more time, divide one of these quarters into quarters, how large of a piece of land would you have?

Answer:10 acres.

Explanation: This has to do with an acre being defined in rods and chains, which are fractions of a mile.

Calculation: There are 640 acres in a square mile. Dividing 640 by four, then by four again, and then by four again, equals 10.
