There will be no dirt in the trench otherwise it would not be a trench.
--------------------------------------------------------------------------
However to dig a trench 960 ft by 6 ft by 10 ft the amount of dirt removed will be 960/3 yd × 6/3 yd × 10/3 yd = 2,133⅓ cu yd.
As you ask about Yard, I guess you are referring to a "builder's yard" which is a cubic yard and are considering the quantity of dirt to cart away. When dug out of the ground the dirt will be loose and not compact and will take up more volume; you will need to order a greater volume of conveyance.

It's a hole, thus there is no dirt in it. The answer is 0.
A yard is 3x3x3 = 27 cubic feet, so 7 yards is 7x27=189 cubic feet
If you were looking for the dimensions of the hole as of a rectangular prism, it would be 3 * 2 * 2 = 12 yards cubed (324 ft cubed).But, there is no dirt in the hole, just the 12 yards cubed that came out of it.
This is the worth math I've ever seen! 1 acre = 43,560 SF, take the square root of 43,560 to give you the base numbers of the acre = 208.71 feet for both the height and width of an acre to get square feet of an acre. Divide 208.71 / 3 = 69.57 yards for the height and width of the acre. Multiply 69.57 x 69.57 = 4,840 square yards in an acre. A cubic yard is simply 4,840 square yards dug down 3 feet or one yard. So one acre has 4,840 cubic yards of dirt if you only dig down 3 feet. If you dig down 6 feet that doubles and so on. One acre would have 48,400 cubic yards of dirt if you dug down 30 feet or 10 yards. Using a one cubic yard example if you removed one cubic yard of dirt from an acre you would have 4,480 cubic yards of dirt, and one cubic yard of dirt weighs approximately 1.3 tons so once cubic acre weighs 1.3 x 4,840 acres = 6,292 tons.

None. It's a hole. 162 cubic feet of air. There is no dirt in a hole.
None because it's a hole but 6 cubic yards of dirt will fill it up.
You are mixing volume (square yard) and area (length x width). How deep do you want the dirt? One foot deep you need about 80 square yards of dirt.
It doesn't hold any dirt. It's a hole.
About 3 yards with a little left over. 2.78 yards.
6 cubic yards of dirt will cover 70 sq ft ... 2 ft 3 3/4 inches deep
The Hellenic trench is about 5000 meters or 16404 feet at the Matapan Deep system.
It depends how big your shovel is. Then, it depends if the dirt is dry or moisty, which can effect everything. and the answer is 360 because 1*3*6= 18 then multiply that by 20. 18*20= 360. your welcome guys.
35,400 feet deep
First off, its Mariana Trench, and it is at 11,033 meters (36,201 feet) deep
39,600 cubic feet. 1,466 cubic yards or about 122 truckloads if it were non-compacted fill.
