If you are going to buy river stone/pebles/rock from supplier they use the "formula"
Cubic Yards x 1.25 = Weight in tons.
They then sell it by the ton. (say $300 per ton)
But this is an approximation. If it is one very big river rock it would be a good approximation, but even then it would depend upon the density of the rock eg granite would require a bigger constant (the 1.25) than a Sandstone boulder.
One cannot weigh "one cubic foot of lava rock." Your cube measures 1 foot in length x 1 foot in width x 1 foot in height; therefore, 1 cubic feet. Not really; it would be almost impossible to measure each lava rock (from a pile) to arrive at 1 cubic foot then weigh them. The generality of your question only requires you to fill a box with lava rock from your garden closest to 1 cubic foot then placing the box of lava rocks on your bathroom scale. It should be lighter than you.
The .5 cubic foot bags of landscaping rocks you can buy weigh 50 lbs.
There is no clear answer for that as all woods are different. For instance compare balsa wood to teak - you WILL feel a difference.
Depends on what the aggregate is. Stone? Screened sand? Lava rock? They all have different weights.
50 pounds
1000 pounds
that depends on th type of sand
You need to know the density of the aggregate. Typically that will be in Imperial system (pounds per cubic feet) or in SI system (kilograms per cubic metre). Use Volume = Mass/Density to convert to volume in the same system. Then convert from SI to Imperial (or reverse) using 1 cubic metre = 35.315 cu ft or 1 cu ft = 0.02832 cubic metre.
Roughly about 30 pounds per cubic foot, so 2 cu ft is about 60 pounds
AnswerOne cubic feet = 40 Kilogram that is One cubic meter = 1411.50 Kg
5280 ft x 5280 ft x 5280 ft x 62.4 lbs per square ft = 9,185,152,204,800 lbs
Approx. 62.42lbs and it all depends on the temperature, the salinity, at what depth and thus the pressure
Solid marble weighs 160 lbs. per cubic ft 160lbs / 2000 lbs/ton = 0.08 tons 1 cubic ft = 0.028316846592 cubic meter 0.08 tons per cubic ft times 1 cubic ft per 0.0283 cubic meter equals 2.83 tons per cubic meter
Nothing by itself. The cubic foot must be full of some kind of matter to have weight. Obviously, a cubic foot of feathers will weigh far, far less than a cubic foot of lead.
8 inches = 2/3 ft 1 cubic yard = 27 cubic ft Volume = (32 x 2/3) cubic ft = 211/3 cubic ft = 0.79 cubic yard
At 62 degrees F (16.7 C,) 1 cu ft of water weighs 62.3 Lb
12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.12 ft * 10 ft * 10/12 ft = 10 cubic feet.
Pu ≈ 19.816 g/cm³ so 1 ft³ · 19.816 g/cm³ · (12 in/ft)³ · 2.54 (cm/in)³ ≈ 561,127 gms or about 1,237 lbs
