What does a 2 x 4 weigh?
Answer . 48
\n. \n How long is it, and from what wood is it made? \n. \nIf we know an object's volume and the weight density of the material of which it is made, we can calculate it…s weight. But to determine the object's volume, we must know more than its width and height (or depth). We must also know its length.\n. \nMost standard two-by-fours are eight feet long, but the type of wood varies. Different woods have different weight densities, and some lumber isn't as dry as it should be. Moisture in the lumber increases its weight density.\n. \nSo, let's assume the 2x4 is eight feet long. A 2x4's actual dimensions are 1.5" x 3.5", so its volume is 1.5 x 3.5 x 96 = 504 cubic inches. Divide that by 12 3 to get 0.2917 cubic feet.\n. \nThe nearby link shows the weight densities of common lumber. Let's assume it's made of pine, which is pretty common. If we use the high end of the range, pine has a weight density of 34 pounds per cubic foot, so 0.2917 x 34 = 9.9167 pound = 158.7 ounces (4.499 kilograms), more or less, depending on the type of pine (Oregon, Parana, Canadian, Red) and the corresponding density. Density tables can be found at a number of sites such as simetric.co.uk, where various material densities can be found, including woods.
use BODMAS brackets of division multiplication addition subtraction. the answer is. 2x2 is 4. 4-4 is 0. therefore 2x2-4 = 0, your final answer. final answer.
Concrete weighs about 150#'s per cubic foot. Given that your measurements are 2'x2'x4', the block contains about 16 cubic feet. 16 cubic feet of concrete at 150#'s is about 24…00#'s per block.
That depends on the density of the board. I can tell you this much: the board's volume is 2*4*8ft, which is 64ft. Feet aren't generally a unit of volume; the fact that they ar…e in this case shows that the board is 1-dimensional. Unless you meant to give the rest of the numbers apostrophes as well, in which case the board's volume is 2ft*4ft*8ft, which is 64ft 3 . Anyway, from that point, you'll need the density to figure out the mass, which you'll need to figure out the weight. That brings up another question: are you talking about weight on Earth? Mehh, you probably are.
It is impossible to answer the question. A solid object has three dimensions (length, breadth and height), only two are given.
Somewhere around 75 pounds
just multiply it,and it equals 40.
It is not possible to answer the question because the measurement units have not been specified.
It depends on the material as well as the force of gravity.

2x4x8/144 = 0.4444 0.444 x 62.4 x .85 ~23.6 lbs
You would use the FOIL method, first outer inner last, to get thisanswer. You multiply the first set of numbers together, then theouter set of numbers, then the inner, and fin…ally the last set ofnumbers. All that's left to do is simplify if needed and in orderof descending powers. So ( a + b ) * ( c + d ) = ac + ad + bc + bd This would give us the answer of... ( x - 2 ) ( x + 4 ) = x^2 + 4x - 2x - 8 = x^2 + 2x - 8
