With a more properly graded 3/4" washed stone (such as a good filter stone ranging between the 3/8" and 1" diameter), you will have a loose drop of more like 75%, but you will also actually be able to get closer to without talking about your subgrade. If the subgrade is sandy, it will not invade such a well graded gravel as much.

To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. The volume formula for a rectangular (or square) box in cubic feet is height (ft) x width (ft) x …
Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and …
The reduction in strength with an increase in PI and in each DR was only obvious for crushed gravel samples and crushed limestone samples with larger voids (i.e., C-CA 2). The reductions in soaked CBR at OMC for crushed gravel (except Sample G) and C-CA 2 samples were up to 35% and 16%, respectively, when PI was increased …

Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve.

Void Ratio. This is the percentage of a water storage tank volume which can be utilised to store water. Typicla values for different storage types are given below. - Storage Tanks. 90-95% - Geocellular Systems. 40-50% - Clean Stone. 30-40% - Uniform Gravel. 20-30% - Graded Sand or Gravel.
The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional ...

Stormwater detention systems often include a large portion of the storage volume within the voids of the backfill material. Depending on the underground structure design and size, allocated storage within the stone voids can vary between 25-60% of the overall storage for the project. The generally accepted number has been 40% stone void space.
This is done by multiplying the area you want to cover (in square meters) by the depth of stone you want to lay (in meters). This gives you the volume in cubic meters. For example, if you want to cover an area of 10 square meters to a depth of 0.5 meters, the volume of stone required would be 10 * 0.5 = 5 cubic meters.
