1 cubic meter of grave contains 50 square meters at 20mm depth (1000mm / 20mm = 50).
2860 / 50 = 57.2
So you need 57.2 cubic meters of gravel.
Depends on what depth you want to spread the gravel at. This answer depends on knowing the cubic capacity of 50 lbs. of gravel.
Gravel is bought in cubic quantities, or by weight. You ask "to fill" but you only give a square measure. The volume of gravel required wil depends on the depth you wish the gravel to be. To fill 81 square metres to a depth of 5 cm would require 4.05 cubic metres of material.
First, you need the density of pea gravel. This depends heavily on particle size and cleanness of the gravel, but a density of 3000lb/yard3 is a realistic estimate. If you want the final answer in metric, it's useful to convert the density to 1780kg/meter3. Knowing this density, you can use it as a conversion factor. You just take the mass of your Pea gravel (for example 50kg) and multiply it by 1 meter3/1780kg to make the units cancel out. Or if you want it easy, just take the weight of your pea gravel in kilograms and divide it by 1780 to get volume in cubic meters. This is a very rough estimate, and actual values depend on the density of the pea gravel being used. The basic idea for any conversion is that you get the density and make sure it uses cubic meters.
A standard dump truck can haul approximately six cubic meters of sand. Sand and gravel are aggregates for foundations in Philippine construction.
Knowing that 1 cubic foot is pretty much equal to 100 pounds or 0.05 ton, 1 ton of gravel is around 20 cubic feet.
The answer will depend on the depth to which the gravel is to be spread.
20 mm = 0.020 meters 18 square meters * 0.020 meters = 0.36 cubic meters
A yard of gravel is the amount of gravel that will fill a container whose inside dimension is 1 yard by 1 yard by 1 yard. It's a cubic yard of gravel. The metric equivalent is .9144 meters by .9144 meters by .9144 meters.

The average cubic meter of pea gravel weighs 1788 kilograms. A cubic meter weighs approximately 1.79 tonnes, and a square meters only weighs 17.88 kilograms or 9.3 pounds.
A "sack" is not a standard unit of measure, sacks come in many sizes. For this reason one can not say in general how many cubic meters of gravel any sack contains.
Gravel is bought in cubic quantities, or by weight. You ask "to fill" but you only give a square measure. The volume of gravel required wil depends on the depth you wish the gravel to be. To fill 81 square metres to a depth of 5 cm would require 4.05 cubic metres of material.
A: One cubic foot. That would be 0.037 cubic yard (rounded)
1 cubic meter of gravel equals to 1400kg or 1.4 tons.
It would depend on the contents of the cubic meter, 4 cubic meters of air would not have a measureable weight, and 4 cubes of sand/gravel would weigh considerably more.
Sand, dirt, gravel and even concrete is measured by the cubic yard and each cubic yard is 1 unit. therefore 1 unit of sand = 27 cubic feet Hence 1 unit of sand = .772 cubic meters
