1.85 cubic yards of cement.
About 3.
For a 4-inch depth you need at least 14.81 cubic yards.
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.
250 feet times 8 feet is 2000sqft, times one inch thick is 166.67 cuft. 166.67 cuft is 6.17 yards. Stone weight approximately 1.25 tons per yard. Therefore, at an inch thick, you need 7.71 tons of pea gravel. 250 feet times 8 feet is 2000sqft, times one inch thick is 166.67 cuft. 166.67 cuft is 6.17 yards.

It depends on the thickness of slab. A yard of cement contains 9 cubic feet. Thus, it would cover 9 square feet if the slab was 1 foot thick. For a 4 inch thick slab, it would cover 3 times as much area, or 27 square feet.
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.
A 14'x14'x4" inch slab will require 2.42 cubic yards of cement.
18x32 feet by 4 inches thick: 7.1 cubic yards. For a 6-inch slab, 10.7 cubic yards.
1237 inches is 103 feet and 1 inch 103 feet is 34 yards and 1 foot, Hence 1237 inches is 34 yards, 1 foot and 1 inch
532.4074 yards of concrete, round up to 533 yards.
