Includes 10% extra for waste. Weight assumes about 1.4 tons per cubic yard (range 1.3–1.5).
The working
12 ft × 50 ft × 6/12 ft = 300.0 cubic feet. Add 10% = 330.0 cubic feet. Divide by 27 = 12.22 cubic yards.

Good to know
A compacted base under pavers is 4 in minimum, and ICPI gives 4–6 in for walks and patios. A paver driveway base is 6–8 in. Loose gravel on a garden path is around 3 in. A compacted base needs roughly 25 to 30% more loose stone than the flat volume (Washington State DOT unit weights), so order extra and ask your supplier.
This row is a paver-driveway base (6 to 8 in compacted, per the Interlocking Concrete Pavement Institute). For a loose-gravel driveway ask a local supplier or your town for the depth: heavy trucks and soft or frost-prone soils need more, and bulk delivery is the only practical way to buy it.
