how many oreos to cover the us
To cover the entire land area of the United States with Oreo cookies laid flat, estimates cluster around about 6 quadrillion Oreos (roughly 6×10156\times 10^{15}6×1015 cookies).
Quick Scoop
- Several independent “Fermi-style” estimates (back-of-the-envelope physics/math problems) put the answer in the 4.8–6.0 quadrillion range.
- One detailed breakdown using standard Oreo size and U.S. land area comes out to about 5.9 quadrillion Oreos , often rounded to “about 6 quadrillion”.
- Another worked solution, which factors in that circles don’t perfectly tile a plane (so you need extra cookies to compensate for gaps), lands around 4.8 × 10¹⁵ Oreos.
In other words, any playful quiz or sweepstakes answer you see that’s in the low single-digit quadrillions is in the right ballpark; numbers in mere billions or trillions are far too small.
How people estimate it (story-style)
Imagine this as a classic internet “they did the math” moment:
- Start with the U.S. land area
- The contiguous U.S. is about 3 million square miles , and the full U.S. land area is often converted into acres or square feet for this kind of puzzle.
- Convert to square inches
- Because Oreos are just a couple of inches across, people convert the national land area into square inches , giving totals on the order of 101610^{16}1016 square inches.
- Find the area of one Oreo
- A standard Oreo is modeled as a circle with diameter around 1.75–2 inches , so its area is only a few square inches.
- Divide total U.S. area by Oreo area
- When you divide “U.S. in square inches” by “Oreo in square inches,” you get a number in the quadrillions of cookies.
- Optionally adjust for gaps
- Since circles leave some empty space when you pack them side by side, some solutions bump the count up to account for that, which is how you see numbers around 4.8 × 10¹⁵ versus about 5.9 × 10¹⁵.
A recent sweepstakes and various Q&A/math-help pages all converge on answers around 5–6 quadrillion Oreos as a fun “official” style estimate.
Mini table: different estimates online
| Source / context | Estimated Oreos | Notes |
|---|---|---|
| Homework-style Fermi solution | ≈ 4.8 × 10¹⁵ | Uses contiguous U.S. area, Oreo diameter ≈ 2 in, adds factor for gaps. | [1]
| Reddit /r/theydidthemath discussion | ≈ 5.7–6.3 × 10¹⁵ | Works in acres and Oreo area, ends up in mid–quadrillions. | [3]
| Forum-style explanation of “US land mass” question | ≈ 5.7 × 10¹⁵ | Framed as the answer to a sweepstakes-style Oreo puzzle. | [5]
| Q&A explainer article | ≈ 5.93 × 10¹5 | Rounded to “about 6 quadrillion Oreos” flat side-by-side. | [7]
Tiny reality check
Just for scale: even one trillion Oreos would already be an unimaginably huge mountain of cookies, so quadrillions is firmly in “thought experiment only” territory.
So, for “how many Oreos to cover the US,” the best short answer that matches current forum and explainer estimates is: about 6 quadrillion Oreos.
