volume of trench = 10' x 3' x 54' = 1620 cubic feet therefore 1620 cubic feet of concrete will be required.
That depends on how deep you want to spread it. On that area, it takes 0.463 cubic yards for every inch deep.
It depends on how thick you want the concrete.
0.246914 cu. yards (6.666667 cu. ft ) of concrete is needed.
You need to specify how deep the area is to answer the question; this is a volume problem. Please ask again
To calculate the amount of concrete needed for a project, you need to determine the volume of the area to be filled with concrete. This can be done by multiplying the length, width, and height of the area. Once you have the volume, you can then calculate the amount of concrete needed by dividing the volume by the coverage area of one cubic yard of concrete. This will give you the total number of cubic yards of concrete needed for the project.

How deep do you want the concrete to be?
To measure how much concrete you need for your project, calculate the volume of the area to be filled with concrete by multiplying the length, width, and height. Then, divide the total volume by the yield of the concrete mix to determine the amount needed in cubic yards or cubic meters.
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
