Why 27 and 324
A yard is 3 feet, so a cubic yard is 3 × 3 × 3 = 27 cubic feet. When the depth is in inches you divide by 12 as well, and 27 × 12 = 324, which is where the shortcut comes from.
One cubic yard is 0.7646 cubic meters, 764.6 liters or about 202 US gallons.

A cubic yard covers 324 sq ft at 1 in deep, 162 sq ft at 2 in, 108 sq ft at 3 in, 81 sq ft at 4 in and 54 sq ft at 6 in.
