It depends on what "5 thick" is: 5 inches thick, 5 feet thick, 5 yards thick, 5 miles thick etc.
Roughly 12 square yards.
I think you mean 6 inches thick, not 6 feet thick. You would need 200 cubic feet, or 7.4 cubic yards.
Total coverage area 314.16 sq. feet. depth of 2 inches = 1.94 cu yards answer ... around 2 cu yards
39.1116 cubic yards

To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.

Depends on how thick it is. At 4 inches thick, you would nee about 5.5 cubic yards adjusting for safety. At 6 inches, you'd need about 8 cubic yards. You can play with different thicknesses with the linked concrete pad calculator.

8.25 cubic yards of concrete
about 26.4 is the volume i think.......
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
1.85 cubic yards...probably 25 bags or so
