Answer & explanation
Official answer
1,820
Oreos
How to estimate it
Fermi’s official “Napkin math”
A queen bed is about 60 by 80 inches, roughly 4,800 square inches. An Oreo is around 1.75 inches across, covering maybe 2.4 square inches. Tuck them together to close the gaps.
- Bed area
- 4,800 in²
- Area of an Oreo
- ~2.4 in²
- Tucked together
- × 0.9
- 4,800 ÷ 2.4 × 0.9
- ≈ 1,800
A queen bed is about 150 by 200 centimeters, roughly 30,000 square centimeters. An Oreo is around 4.5 centimeters across, covering maybe 15 square centimeters. Tuck them together to close the gaps.
- Bed area
- 30,000 cm²
- Area of an Oreo
- ~15 cm²
- Tucked together
- × 0.9
- 30,000 ÷ 15 × 0.9
- ≈ 1,800
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Queen mattress area
- 60 × 80 = 4,800 in²
- Area of one Oreo
- ≈ 2.4 in²
- Hexagonal packing efficiency
- × 0.91
- 4,800 ÷ 2.4 × 0.91
- ≈ 1,820
