depends on your spacing, 16" on center or 24" check your local building codes...and what your deck application is..Are you using a composite decking or wood..Couple of variables play into this...------------------------------------I'll Play:Assuming 16" on center...If you are using 8 foot 2x6's you will need 19.If you are using 12 foot 2x6's over lapping 1 foot to make the 23" and supported along the center of the room you will need 14.For 12" on center: 24(8ft) or 18(12ft)For 24" on center: 13(8ft) or 10(12ft)Note: depending on design/support, 2X6 may not be big enough for code (or safety).
1x12, 2x6, 3x4, 4x3, 6x2 1x12 1x12, 2x6, 3x4, 4x3, 6x2 1x12
1x12 2x6 3x4
If the temperature dropped 2 degrees Fahrenheit every hour for 6 hours, the temperature would change 12 degrees. You multiply 2x6 to get the answer of 12.
A nominal 2x6 baord is actually 5.5" wide. 5.5"/12"=0.45833ft => 0.45833ft x 300ft = 137.5 sq-ft

you build forms,lay in rebar,pore concrete,put in J bolts,to bolt your 2X6 pressure treated wood to.then floor joists.
Usually there are 10 in a bundle.

Evation: n+7-(2x6) Answer: 0
It's unlikely you would use many 2X4s on a deck. The joists (under the decking) are usually 2X6 or larger. The larger the joist, the fewer you need, because you can space them further apart. The decking is made of 1X6s nailed or screwed to the top of the joists, and running perpendicular to the joists or at an angle to the joists. The amount of decking you need depends on whether you intend to make a pattern (herringbone) or a typical deck. The railing might include 2X4s as the top rail, but the support posts are usually 4X4s, and in between those, you usually use small stock to add the decorative posts/slats.
