The base of the patio is to be a slab of concrete 24 feet long by 18 feet wide by 6 inches thick. If one cubic yard of concrete costs $42, how much will the concrete for the patio cost?
3 feet = 1 yard
12 inches = 1 feet
Concrete needed = (24)*(18)*(0.5) = 216 ft^3
1 yrd^3 = 3^3 ft^3 = 27ft^3
216/27 = 8 yrd^3
42*8 = $336
