The title and one place in the body call it 500 acre, while one other place calls it 500 mile. 500 square miles is 320,000 acres. (500 miles) squared is 160,00

The title and one place in the body call it 500 acre, while one other place calls it 500 mile. 500 square miles is 320,000 acres. (500 miles) squared is 160,000,000 acres. One other place in the body refers to 1,600,000 acres being viable to reforest. I think it was just a typo for 500 acre.
