Volume of slab = 18 feet * 18 feet * 6 inches = 6 yards * 6 yards * 1/6 yards = 6 cubic yards.
Cost of 1 cubic yard = $42
Cost of 6 cubic yards = $42 * 6 = $252

18 feet = 18/3 yard = 6 yard
6 inches = 1/2 feet = 1/6 yard

Volumen = (6yar)(6yard)(1/6yard) = 6 cubic yard

Cost = 6 cubic yard * $42.00 / cubic yard = $ 252.00

Answer: the first option, 252.00
