This is a problem to find volume.
First convert all numbers into yards:
9 feet = 3 yards
12 feet = 4 yards
6 inches = 1/2 foot = 1.5 yards
Now multiply everything together:
3*4*1.5 = 18
18 cubic yards of concrete.

9 feet = 3 yards
12 feet = 4 yards
6 inches = 1/2 foot = 0.166667 yards (Since 3 feet = 1 yard)
So Volume = 3*4* 0.166667 = 2.000004 ~ 2 cubic yards.
12 feet = 4 yards
6 inches = 1/2 foot = 0.166667 yards (Since 3 feet = 1 yard)
So Volume = 3*4* 0.166667 = 2.000004 ~ 2 cubic yards.
