A general rule we used in building material sales figures it at 3.5 lbs per board ft. To figure board footage, Multiply Width * thickness * length, divided by 12 for board ft. For Example, a 6x6x16 = 48 Board feet. 48 board feet * 3.5 = 168 lbs. 168 lbs for the entire 6x6x16'. So 168/16 = 10.5 lbs per linear foot of 6x6. Ofcourse, this is only a general rule, and may vary due to the amount of retention (treated chemical forced into the board) and overall moisture of the product. Some of the newer treatments such as MCA treatment weighs significantly less than some of the older Heavy Retention, because it is supposedly a better preservative and therefore less is needed to adequately protect it from the elements.

It depends if you are talking about pre-1982 pennies or post-1982 pennies.
An exact answer to your question is difficult because there are many factors that must be taken into account, but we can guestimate an answer. Different types of wood have different densities. I believe that most of the posts sold in home improvement stores like Home Depot or Lowe's are Southern Yellow Pine or Cedar. You have to also take into account the moisture content of the wood. Most treated wood sold at home improvement stores is Grade 2 and, when green, has a moisture content of 17% to 20%. You can feel the heaviness and moisture in the wood when you pick up a fresh post. This moisture in the wood adds a lot of weight. And, of course, the length of the post makes a difference. For this example, we'll assume an 8' post. Southern Yellow Pine (SYP) has a density of 36 to 41 pounds per cubic foot with a 20% moisture content. Naturally, as the wood dries out and with low humidity, it will weigh less. We'll use an average of 38.5 pounds per cu.ft. Calculate the volume of wood. Actual (not nominal) size of the post is 3.5" x 3.5" x 96" = 1176 cubic inches. One cubic foot = 12" x 12" x 12" = 1728 cubic inches. Divide 1176 cu.in. by 1728 cu.in. = 0.6806 cubic feet. Calculate weight. 0.6806 cu.ft. x 38.5 pounds per cu.ft. = 26.20 pounds. So, a 8' 4x4 post made out of SYP with a moisture content of around 20% weighs somewhere in the neighborhood of 26 pounds. HTH.
It would depend on the denominations of the coins. Post new question with more information.
The density is (the mass of a piece of the foam)/(the volume of the same piece).The size of the piece doesn't matter.
Different woods will have different weights. On average, the post will weigh about 54 pounds.
Look on the driver's door post.
60 cards might weigh about 3.5oz, but you can always take the card to the local post office to weigh card or cards. 1 card could weigh about .058oz. maybe, best to weigh at Post Office though.
The weight is listed on the drivers door post.
Look on the driver's door post.
The weight of the vehicle is listed on the drivers door post.
You need to provide more information - length and diameter or dimensions across flats of the post. I can then tell you roughly what it will be.

Need diameter as well.

Weigh
One modern (post-1982) US cent weighs 2.5 grams, so 4,000 pennies weigh 10,000 grams, or 10 kg.
