A 15 × 16 room: 240 square feet and two uses
Fifteen by sixteen is 240 sq ft, the size of a family room or of a living and dining room sharing one space. A 10 × 14 ft rug nearly fills it, with 2.5 ft of floor at the sides and 1.0 ft at the ends; two smaller rugs do a better job of marking a seating area and a table. The room measures 62 ft around and 21.9 ft on the diagonal.
Both sides are whole feet, so 12 in tiles fit without a cut row if the walls are true: 240 tiles to cover the floor and 264 with the usual tenth for breakage and trimming. Plank flooring comes to 264 sq ft, which is 14 boxes, heavy enough to have delivered. The walls total 496 sq ft at 8 ft, and two coats on the 445 sq ft left after openings need 2.54 gallons, so 2 gallons + 3 quarts. Ceiling paint adds 1.37 gallons.
