To cover the entire land area of the United States with Oreo cookies, the estimated number is approximately 2.8 billion Oreos. This figure was cited in an Oreo sweepstakes as the correct answer to the question of how many Oreos it would take to cover the U.S. land mass
. This estimate aligns with calculations based on the total U.S. land area (about 3.7 million square miles) and the surface area of a single Oreo cookie (roughly 2.5 square inches). When converted and calculated, the total number of Oreos needed to cover the U.S. surface comes out to the order of billions, specifically around 2.8 billion Oreos
. In summary, about 2.8 billion Oreo cookies would be required to cover the entire United States.
