Since there are 3 feet in 1 yard the distance 14 ft = 14/3 = 4.66667 yards.
14ft * 22 ft = 14*22 sq ft = 308 sq ft = 308/9 = 34.2... sq yards.
The volume of the hole is (782 x 1.5) = 1,173 cubic ft. 1 cubic yard = 27 cubic ft 1,173 cubic ft = (1,173 / 27) = 43.444 cubic yards (repeating)

Divide by 27.
To determine how much cement you need for a 14ft x 9ft area, you'll first need to know the thickness of the concrete slab you plan to pour. For example, if you're pouring a 4-inch thick slab, you'll convert the dimensions to cubic feet: 14ft x 9ft x (4/12)ft = 42 cubic feet. Since one cubic yard equals 27 cubic feet, you'll need about 1.56 cubic yards of cement, which you can round up to 1.6 cubic yards for practical purposes. Make sure to account for waste and variations in the mix, so it's advisable to order slightly more.
