Why does a bag of cement weigh 94 pounds?
The weight of a 94 lb. sack of cement is incidental - the bag is packaged in that size in order to hold one cubic foot of cement, and 94 pounds is simply what one cubic foot of dry cement powder weighs. Mix design for concrete was originally performed by volume and not by weight. Mix designers were initially concerned about variations in density and thought volume would deliver the most consistent results. As time progressed, they found that mix design were not adversly affected when designed by weight, (which was also much simpler), and therefore became used industry wide. Because 94lbs of cement is, as noted above, what 1 cubic foot of cement weighs, the 94 lb sack was a backhanded way for the mix designers to check the weight calculations easily with known volumes.

What is the specific density of air?
The density of dry air is 1.29 grams per liter (.07967 pounds per cubic foot) at 32° Fahrenheit (0° Celsius), average sea level, and average barometric pressure (29.92 in of mercury [760 millimeters]). The weight of 1 cubic foot of dry air at 1 atmosphere of barometric pressure is:Temperature (Fahrenheit)Weight per cubic foot (pounds)50° 0.0778860°0.0764070°0.07495
1.5 cubic feet of soil is how many pounds?
The weight of soil can vary depending on its composition and moisture content. However, as a general guideline, the average weight of dry soil is approximately 75 pounds per cubic foot. Therefore, to calculate the weight of 1.5 cubic feet of soil, you can multiply the weight per cubic foot (75 pounds) by the volume (1.5 cubic feet): Weight = Volume × Weight per cubic foot Weight = 1.5 cubic feet × 75 pounds per cubic foot Weight = 112.5 pounds So, approximately 1.5 cubic feet of soil would weigh around 112.5 pounds. Keep in mind that this is an average estimation and the actual weight can vary depending on the specific characteristics of the soil.
Weight of 40 yard dump truck Weight loaded with 40 yards of soil Weight loaded with 40 yards of concrete?
Don't know the weight of the truck alone -- google it. Concrete (wet) could be assumed to be 145 pounds per cubic foot, and there are 27 cubic feet in one cubic yard. Compacted damp to dry soil (at "optimum moisture" for compacting) might run around 110 to 120 pounds per cubic foot, and loose soil would be considerably less (assuming it's dry and not saturated).
How many pounds does a cubic meter of wood weigh?
Each type of wood has a different weight per unit volume. Some commonly used kinds of wood are pine, fir, spruce and cedar. Pine weight ranges from 27 to 45 pounds per cubic foot. For one cubic meter, multiply by 27. Douglas fir weighs about 33 pounds per cubic foot. Spruce (dry) weighs 28 pounds/cubic foot. Red cedar weighs 24 pounds/cu. foot.
What is density of one cubic meter of cement?
Daft question really! Should be what is the density of cement. Does the question mean cement ( dry powder), wet concrete, set concrete or what?
How do you proof that 1 cu ft of dry cement is 94 lbs?
You go to either Home Depot or Lowe's and buy a bag of Portland cement - preferably one with no holes. There's one cubic foot in that bag, as stated clearly on the label, and it weighs 94 lbs.
