A standard 2x4 x 8' piece of lumber typically weighs around 9 to 10 pounds, depending on the type of wood and its moisture content. For example, a dry pine 2x4 of this size is generally on the lighter end of that range. Keep in mind that different wood species may have slightly different weights.

1 3 / x / 2 4 Multiply the numerators and then the denominators Numerators: 1x3 =3 Denominators: 2x4 =8 So the answer is 3/8 which is 3 ovr 8
If you mean '2x4' as in 2 times 4- 2x4= 8 3x3= 9 4x2= 8 8-9-8=-19 if you want to divide by x -b/c x doesn't have a set amount- it would be: -19/x
Take the sum in stages.2x4 is 8.8-8 is 0.
