Need to know the specifics of the dump truck you had in mind. Tandem axle dumps in the company I work for... if they have a 'dirt tub' body, they can carry 16 cubic yards. The ones with the 'rock tub' dump bodies can carry 15 cubic yards.
It depends on the size of the dump trucks, but assuming a standard dump truck can hold about 10-15 cubic yards of dirt, it would take approximately 260,000 to 390,000 dump trucks to move 3.9 million cubic yards of dirt.
How much dirt a dump truck holds will vary based on the size of the truck. Small dump trucks can hold around 7 cubic yards. Large double axle dump trucks can hold up to 20 tons.
To calculate the volume of dirt needed to fill the area, you would need to know the depth of the area in yards. If the depth is 3 yards, then you would need 1800 yards of dirt (600 cubic yards รท 3 yards). If the depth is 1 yard, then you would need 600 yards of dirt.
A dumper truck is used to carry and transport materials such as gravel, dirt and sand in construction. You can get more information about dumper trucks at the Wikipedia.
400 yards of dirt would be a pile that is 1 yard wide, 1 yard tall, and 400 yards long. This would equate to roughly 1,200 cubic yards of dirt.
577 yards.
There is about 2800lbs in 2 yards of top soil.
None because it's a hole but 6 cubic yards of dirt will fill it up.
The weight of dirt can vary depending on the type of dirt, but on average, 1 cubic yard of dirt weighs about 2,000 pounds. Therefore, 2.5 yards of dirt would weigh approximately 5,000 pounds or 2.5 tons.
There may be very little or even none . Topsoil and "dirt" are different substances
14 cubic feet = 0.518 cubic yards
