Best ResponseYou've already chosen the best response.0B. First convert the patio slab into feet. We know that there are 12 inches in 1 feet. We convert 2inches into units of feet 17ft X 17ft X 2 in (1ft/12inches) = 48.2 cubic feet We then convert 48.2 ft^3 into cubic yard. We know there is 3 feet in 1 yard. 48.2 ft^3 X ( 1 yard / 3 feet)^3 = 48.2 ft^3 X (1 yard^3 / 27 ft^3) = 1.79 cubic yard To figure out the cost. We have 1.79 cubic yard for the patio. 1.79 yard^3 X ($40/yard^3) = $71.4

Best ResponseYou've already chosen the best response.0You need to find how many cubic yards is the volume of the slab. Then multiply the cost per cubic yard by the number of cubic yards. \(V = LWH = \left( 17~ft \times \dfrac{yd}{3~ft} \right) \times \left(17~ft \times \dfrac{yd}{3~ft} \right) \times \left( 2~in. \times \dfrac{yd}{36~in.} \right) = 1.78 ~yd^3\) \(Cost = V \times (cost ~per ~yd^3) = 1.78 ~yd^3 \times 40 \dfrac{$}{yd^3} = $71.36\)
