None. Because 'yars' is a linear measure. You need a 'Cubic' measure.
You gave two dimensions a length and a width. However, you also need to know the depth, in order to give you the volume of concrete needed in 'cubic feet'.
To convert 'cubic feet' to 'cubic yards' divde cubic feet by '27'.
You will need 1.23 cubic yards.
Most will hold 10 cubic yards. Some local codes will force them to run 8 or less because of the weight.
Total surface area... 276 square yards.
8 yards square
16 hectares is 191358 sq yards. It is not possible to give the length and breadth since the area could be, for example, 1 yard by 191358 yards or 10 yards by 19135.8 yards or 100 yards by 1913.58 yards or 2 yards by 95697 yards
This area requires 2.5 cubic yards.
You will need 1.23 cubic yards.
10 yards
8 square yards
You'll need 1.23 Cubic Yards.
10 cubic yards for every 1 foot of height.

10 cubic yds per load
3.70 yards and you will order 4 yards to have enough. (30 x 10 x 1/3) = 100 cubic feet Divided by 27 = 3.704 cubic yards
1.85 yards (.5 x 10 x 10 ) divided by 27 where .5= the 6 inches converted to feet and 27 is the conversion to cubic yards. Concrete volume is measured in yards, which actually refers to a cubic yard (1 yd x 1 yd x 1 yd).
The area of a cylinder with a radius of 6 yards and a height of 10 yards is 603.19 square yards.
