Yes.
1 and a half inches by 3 and a half inches. Note that an "8 foot 2x4" is 8x12" = 96" long, but a "2x4 stud" is 92 5/8" long to allow for bottom and top plates to make wall framing go quicker.
A 2X4 would be a stud, not a board. Weight depends on the length and species, if it is pressure treated or not. 8ft. hem-fir 2X4 is about 8 pounds or so.
Can be eight or eleven feet long. In actuality, it can be as long as you want. 2x4 refers to the width and height dimensions of the plank, not the length. So I could cut a 2x4 to 2 inches long and it would be a 2 inch long 2x4.
It varies. Is it yellow pine,spruce,and wet or dry ? A 2X4 Spruce/ Pine/ Fir KD 1.375 lbs per foot ( Used for interior building in projects New England ) 2x4 Pressure Treated southern yellow Pine 2.175 lbs per foot. (Used for exterior building projects ie. Deck railings) That actual weight will vary depending on exactly which species, and how dry / wet the wood is. But these are generally excepted weights we use in calculating shipping weight for these types of wood.
A 2x4 piece of wood.
2x4's weigh approximately 1.21 pounds per foot. So an 8 Foot 2x4 = 9.68 pounds 12 Foot 2x4 = 14.52 pounds 14 Foot 2x4 = 16.94 pounds Just take 1.21 pounds times the length of the board and this will give it it's overall weight. This is for pine boards.
2x4x20/12= 13.33 bdft.
A yellow pine 2x4 can swell to about 0.1% to 0.2% of the original size. It is important to note the swelling and shrinkage of any type of wood before using it.Ê
a normal 2X4 weights between 8 to 10 pounds
2x4's have a weight that varies based upon wood and length. With this said, the weight generally runs at about one point twenty-eight pounds per foot in length. Thus, an eight foot 2x4 would run about eleven pounds.
256 feet
You still need to indicate the pitch, the roof sheathing, and the shingle weight.
A "board foot" is 1 inch thick, 12 inches wide, 12 inches long. A 12 ft 2x4 would be 8 board ft- 1/3 the width, but 2X the thickness.
