A 10 × 10 ft room with 8 ft ceilings has about 284 sq ft of paintable wall after subtracting a door and a window. For 2 coats at 350 sq ft per gallon, that's about 2 gallons (≈ 7.57 litres).
How many gallons of paint for a 10x10 room with two coats?
About 2 gallons. Buy in gallons rather than quarts — they're much cheaper per square foot — and keep a little extra for touch-ups.

Prime bare drywall, patched spots, and big color changes. Count primer as an extra coat at similar coverage — roughly another 2 gallons for full coverage.
