Well you have not mentioned the thickness of the board so as a rough idea the weight of 10'x4 pine board with 12 mm thickness is appx. 60 kg. For complete answer you may ask experts at http://www.gharexpert.com Regsasrds
0, -1/10, 2/10, -3/10, 4/10, -5/10, 6/10, -7/10, 8/10, -9/10, 10/10, -11/10
a + 4 = 10(a + 4) - 4 = 10 - 4a = 6
-4-x = 10 -x = 10+4 -x = 14 x = -14
4(x- 8) + 10 = -10
Answer is 6 here, x - 10 = -4 so, x = -4+10 x = 6
about 1.2 pounds
Im building a bench. Im using 2"x10" pine. Is 5' between braces strong enough? It depends on how many boards your are putting on your bench. To give you an idea, I ran through some quick numbers for you. @ 5'. one 2" x 10" x ?? pine board assuming a 400lb load (2-3 people) you will have deflection of .42" PER board which is fine. Less than 1/2 inch. @ 4' your deflection is reduced to .22" PER board which is even better. You really shouldn't have a problem at 5', unless a 400lb guy jumps on the middle of your bench. The maximum weight it will take in the middle before fracture is 688 lb @ 5'/brace and 860 @ 4'...and keep in mind this is per board so if you have two....you should be fine. This is as long as it is standard pine. .
Once it's kiln dried, yellow pine is one of the lighter woods. I wouldn,t think a 4x12x10' should weigh much more than 60 lbs. Maybe not that much. Sorry, but the above answer is incorrect. Actually the weight of dried southern yellow pine is around 3 lbs per board foot. A 4x12x10' contains 40 board feet and therefore weighs approximately 120 lbs. The above answer is conservative. The exact answer is yellow pine has a density of roughly 40lbs/ft^3. A 4x12 is actually 3.5"x11.25" = 39.38in^2. Therefore for a 10ft section: (40lb/ft^3) x ((39.38in^2)/144) x (10') = 109.4 lbs.
The weight depends on the type of wood. Pine weighs less than oak.
It would depend on the material the board is made from. 1 x 18 pine boards are used for wide shelves and can support a lot of weight, but will sag at lengths of 4 feet or more unless they are center braced.
if youre taking about weight no
Cubic Feet = Area (ft) X Height (ft) / 4

A 2 by 4 (lumber) will have a weight based on the density of the wood. Pine, fir, redwood, treated or untreated will have different densities.
thickness and type of wood are varibles oak and maple are heaver than pine 3/4 is heaver than 1/4 and 1/2
4 to 6 is the pH of pine trees
