It depends how thick you want it
You will need at least 14 cubic yards.
For a 4-inch depth you will need at least 7 cubic yards.
Oops . . . please repost your question and include the depth of the concrete. You have to have all 3 dimensions in order to calculate volume (Cubic Yards of concrete).
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.
Well assuming the depth of concrete is going to be 1 meter you will need 846 cubic meters of concrete.
1 cubic yd of a concrete mixture contains about 500 hundred lbs of cement

You will need at least 14 cubic yards.
Mass is: M=V x d.To calculate the mass you need to know the density of this concrete and also the volume.
For a 4-inch depth you will need at least 7 cubic yards.

My Astronomy professor says that we need at least 15 feet of concrete to block nuclear radiation.
Flatwork = Total square feet (L x W) x .33 (4 ") / 27 = yards concrete
