Assuming that the question is being asked about "dirt"; in the United States, the volume of dirt is calculated in cubic yards. In the rest of the world, the volume of dirt is calculated in cubic meters.
A cubic yard of dirt is the volume of dirt that fits in a space 1 yard (36 inches) by 1 yard by 1 yard.
A cubic meter is 1M X 1M X 1M.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
# 10 bare copper.
Use #10 copper.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
#6 bare copper wire.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
For a 20 amp circuit, a 12-gauge copper ground wire is typically recommended. This wire size can safely handle the current and provide proper grounding for the circuit.
For carrying 100 amps underground, typically a 2-gauge copper wire or a 1/0-gauge aluminum wire would be suitable. It's important to consult with a licensed electrician to ensure the correct wire size based on distance, voltage drop, and local electrical codes.

# 10 bare copper.
How to calculate a cable size of 3kw motor
Both 12-2 and 14-2 wire have 2 wires in a single cord. Neither contains a ground wire. Size 12 wire is a larger wire than size 14 wire. Size 12 wire can carry more amperage without getting hot and burning up. They would not be used for house wiring or machinery since they do not have a ground wire.
You need to know the amperage requirement of the pump and then you can calculate the wire size.
Use #10 copper.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
