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.
volume of trench = 10' x 3' x 54' = 1620 cubic feet therefore 1620 cubic feet of concrete will be required.
The depth is less important than the proper shoring up of the trench sides. Even a shallow trench can collapse and trap a worker if the sides are not shored up properly.
6.67 cubic yards
300m3
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.
The trench is 35,600,056 ft deep
the answer i Izu the trench
The Puerto Rico Trench is an oceanic trench located on the boundary between the Caribbean Sea and the Atlantic Ocean. The island of Puerto Rico lies immediately to the south of the fault zone and the trench. The trench is 800 kilometers (500 mi) long and has a maximum a depth of 8,605 meters (28,232 ft) at Milwaukee Deep, which is the deepest point in the Atlantic Ocean.
Marianas Trench
It is in the Mariana Trench!
about 6 miles deep
The deepest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench at a depth of 10,911 m (35,798 ft) below sea level.Underwater the Marianas Trench would be the deepest Trench in the World.Challenger Deep's Deepest part is about 35,838 feet deep (11035 meters).The deepest point in any ocean is the Mariana Trench (aka Challenger Deep) in the western Pacific Ocean at 11,033 metres deep.
First off, its Mariana Trench, and it is at 11,033 meters (36,201 feet) deep
when two oceanic plates collide they create a deep-ocean trench, at deep-ocean trenches subduction occurs.
The Hellenic trench is about 5000 meters or 16404 feet at the Matapan Deep system.
35 838ft/10 923m deep. the deepest point in the trench is the challenger deep
