Rafters are usually on 2 ft. centers.
A nominal 2x6 baord is actually 5.5" wide. 5.5"/12"=0.45833ft => 0.45833ft x 300ft = 137.5 sq-ft
The maximum span for a 2x6 lumber member used as floor joists, spaced 16 inches on center, is typically around 9 feet for residential applications, depending on the load conditions and wood species. For ceiling joists, the span can be slightly longer, usually up to 10 feet. It's important to consult local building codes and a structural engineer for specific requirements and safety factors.
Well, it could be any 2+ sided shapes. A square (4x5), a rectangle (2x6 then 2x4 perhaps?), or any other shape.
3 or 6, depending on whether rectangles rotated through 90 degrees are counted as different. The rectangles are 1x12, 2x6 3x4 and their rotated versions: 4x3, 6x2 and 12x1.
Over a century and a half ago, wood was milled a true 2" x 4" ....thus 2x4 .....the same with 2x6, 2x8 ....and so on. However it was "rough sawn" lumber. Wood size standards came about in the 1920 's or so. still made chnges in the mid 60's But the need for more finished lumber drove sawmills to go through another step in the milling process.. saw mills were crude and milled in crude dimentions. if the mill surfaced one side it was S1S......Surfaced ! Side.... S2S ..and so one. Economics was the real player in all this ...The new surfaced sizes became the standard...
