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.
It is the dimensions that are given in natural numbers or non-negative integers. So no fractions. Such as the room is 2x4 feet NOT the room is 2.5x 3.2 feet or 2 1/2 x 3 1/4 feet

You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
17 2x4=8+(3x3)=17 3x3=9 9+8=17
Well, honey, a standard ruler is typically 12 inches long, which is equivalent to 1 foot. So, an object that is 2 feet long would be something like a yardstick or a baseball bat. Just make sure you don't go around swinging that thing indoors, unless you're looking to redecorate with some broken vases.
2x4x20/12= 13.33 bdft.
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.
Linear footage as referred to in wood or lumber is the length as you see it.For instance a 2 x 4 x 8, is 8 feet long. - In theoretical board feet this is actually 5.333 board feet or practically, 5.0 board feet. ( because a 2x4 is not really that dimension, but 1.5x3.5. )
The nominal size of a board is used to calculate board feet, not the actual size. Nominal dimensions refer to the board's rough-cut measurements, typically expressed in inches (e.g., 2x4), while the actual size is smaller due to milling (e.g., a 2x4 actually measures about 1.5x3.5 inches). To calculate board feet, you multiply the nominal dimensions and the length of the board in feet, using the formula: (Thickness in inches × Width in inches × Length in feet) / 12.

A standard unit of lumber, often referred to as a "lumber unit" or "board foot," typically contains 1,000 board feet. Since a 2x4 measures 1.5 inches by 3.5 inches and is usually 8 feet long, it equals 5.33 board feet per piece. Therefore, a unit of lumber contains approximately 187 pieces of 2x4s, assuming standard lengths and no waste.
The number of board feet in a bundle of pine lumber can vary based on the dimensions and quantity of the boards in the bundle. To calculate board feet, use the formula: Board Feet = (Thickness in inches x Width in inches x Length in feet) / 12. For example, a bundle containing multiple 2x4 boards that are 8 feet long would have a different total than a bundle of 1x6 boards at the same length. It's best to check the bundle specifications or calculate based on the dimensions provided.
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.
A 2x4 wood board typically has dimensions of 1.5 inches in thickness and 3.5 inches in width.
OH, and its about 7 feet high
