Suppose that depends on what one means by "just a few acres of land"

An acre is 43,560 square feet. If everyone is given a 2 foot square (meaning a square 2 foot x 2 foot or 4 square feet?) then 10,890 people could stand in an acre. You'd need a bit more than 550,000 acres to hold 6 billion people. That's about 860 square miles or a square a bit less than 30 miles on a side.
