Answer:
80 acres
Step-by-step explanation:
To resolve the problem, you need to know how many acres are in a section and what fraction of that is the land of the problem.
There are 640 acres in a section.
One half of the one half of the one half is: 1/2 * 1/2 * 1/2 = 1/8
One eighth of a section is: 1/8 * 640 acres = 80 acres.
