The way to fill a trench with gravel depends on the purpose of the trench and how much drainage you need. For example, in wetter soils you'd need a deeper layer of gravel than in drier soil. Generally, for a trench where water or sewer (such as for a backyard pit) pipes are laid in the trench, about 2 to 3 inches of moderate sized gravel would work. If you are intending for the trench to act as drainage around or near plants, 1 to 1.5 inches of gravel may help provide adequate drainage.
When my dad and I laid sewer pipes, we used 3" in clay soil (which holds more moisture/rain). Lay the gravel first, leveling it as much as possible. Make sure to increase or decrease on sloping land, as needed. Lay and join the pipe, making sure the pipe is at a slight downward angle from any building. Continue joining pipe along the length. It is important to TEST the pipe at this point to be sure the connections are secure; run water from a hose, run water from the house, or flush a water-only toilet (no waste in toilet). Once the pipe was tested, my dad then added a layer of gravel on top of the piping, to a 1.5 inch depth. Then, shovel in topsoil and gently pack (tamp) down.
The amount of time that gravel can retain water will vary depending on its state. Fine gravel will holder water for long as opposed to coarse gravel.

It is a trench filled with gravel or rock containing a perforated pipe that redirects surface and groundwater away from an area. Generally used for keeping water away from building foundations. They can also be used behind retaining walls to relieve ground water pressure
Gravel occupies about 70-80% of the volume of concrete.It makes concrete economicalStrength of the concrete is determined only by the gravel. i.e., the body of the concrete.Property of concrete determined by the type of aggregate used.Shrinkage is less when larger size aggregate is used.
That's not enough information. You need to know the width of the trench, and how much volume 1 ton of gravel is equivalent to.

The formula for water is H2O. Gravel can be any form of stone or rock so the formula for that would vary.
A French Drain is simply a gravel filled trench that crosses a property to remove water. The gravel provides porosity and the trench the directionality. With todays geotextile fabrics it would be possible to put a porous membrane across the op of the trench to keep it from silting up while providing the option for a sod grass cover.

Decide on the size and location of your trench. Measure the location and decide how deep and wide your trench should be. Clear the area of any debris or obstructions. Dig your trench. Use a shovel, pickaxe, or other digging tools to excavate the soil. Make sure to maintain a deep, consistent depth throughout the entire trench. Line the trench with sandbags. Place sandbags along the sides of the trench to reinforce it and provide a protective layer. Line the bottom of the trench with sand or gravel. This will help with drainage and prevent the walls of the trench from caving in. Add any additional reinforcements, such as wood or metal beams. Add a roof or overhead cover to protect soldiers from enemy fire. Add any additional features, such as dugouts, communication posts, or fire steps. Cover the trench with dirt or soil. This will help to conceal it and keep it from being an obvious target.
No, I had this as a choice in a check all that apply question and it is a junk answer meant to trip you up. The ways are structural formula,molecular formula,empirical formula,space-filling model,ball and stick model. Cheers.
A trench stretch is a long system of trench.
A rubble drain is also called a French drain, blind drain, rock drain, drain tile, perimeter drain, land drain or French ditch. They are constructed by digging a step-sided trench, filling the trench with loose stones, and covering the stones with earth.
