288 square feet, twice as long as wide
Twelve by twenty-four gives 288 sq ft. You see it as a deep single garage with a workbench at the back, a large shed, a single-wide addition, or the main floor of a small cabin. It is 72 ft around. Everything is arranged along the length: in a cabin that might be a kitchen at one end, living space in the middle and a sleeping area at the far end.
As a slab it needs roughly 3.9 cubic yards at 4 in. As a finished interior the floor takes 16 boxes of plank, and running the planks the long way gives the fewest end cuts. Walls at 8 ft are 576 sq ft gross, and with one door and two windows removed two coats use 3.00 gallons. That is past the point where a 5 gallon pail starts to make sense next to single cans (the exact buy is 3 gallons).
