Concrete delivered to a construction site costs $250 a cubic yard. What is the cost of the concrete needed to build a 6-inch-thick patio slab 20 feet by 10 feet?

Additional information: The volume of a rectangular slab is the product of its three dimensions. The 6 inches thickness of the slab is 1/2 foot thick Preliminary calculations Compute the volume in cu ft for the entire job 20 (ft) * 10 (ft) * 1/2 (ft) = 100 (cu ft) Since this is the entire job 100 (cu ft /job) Note: An alternative approach would be to include the volume calculation in the equation below. However, doing it as a preliminary calculation seems more straight forward.
