What does a 2 x 4 weigh?
It means that the truck does not have four wheel drive. The truck is rear wheel drive and is pushed from the back. 4x2 means a four-wheel vehicle in which engine power is tr…ansmitted to only two axle-ends: the front two in front-wheel drive or the rear two in rear-wheel drive.
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 ab…out 2400#'s per block.
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.
about 70 pounds
It just means that it is a 2 wheel drive Jeep.
Somewhere around 75 pounds
A 2x4 matrix has 2 rows (horizontal) and 4 columns (vertical). Ex: [1 2 3 4] [5 6 7 8]
X + 4(x) + 2 x+ 4x + 2 5x + 2
How long is it, and from what wood is it made? If we know an object's volume and the weight density of the material of which it is made, we can calcul…ate its 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. Most 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. So, 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 123 to get 0.2917 cubic feet. The 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.
around twenty kgs
8 fifths. 2/1 X 4/5 Multiply the numerator. (top) 2 X 4= 8 Multiply the denominator. (bottom) 1 X 5= 5 Put numerator and denominator together. The answr is 8/5, …which is an improper fraction. You can leave it like that in Algebra, but if you want ot simplify it more, divide 5 into 8. 1 3/5 is the more simplified answer.
In lumber, a 2x4 represents the width and height of the wood. The last number describes the length. A 2x4x8 is eight feet long.
