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)

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. )

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.
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
20x20 = 400 2x4= 8 400/8= 50 needed

To calculate the board feet in a 40-foot wall, you need to determine the height and thickness of the wall. Board feet is calculated using the formula: (width in inches × height in inches × length in feet) / 12. Assuming a standard wall height of 8 feet and using 2x4 lumber (which is actually 1.5 inches by 3.5 inches), the calculation would be: (3.5 × 96 × 40) / 12, resulting in approximately 120 board feet for a single layer of studs.
The standard size of a 2x4 wood board used in construction projects is actually 1.5 inches by 3.5 inches.
