+2448 Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 18 feet by 18 feet by 4 inches for a patio if the concrete costs $41.00 per cubic yard? a. $738.00 b. $4428.00 c. $492.00 d. $164.00
+128408 First, let's convert feet to yards
Remember 3ft = 1 yd....so divide ft by 3 to get the yards
18 feet / 3 = 6 yds
4 inches = 1/3 ft / 3 = 1/9 yds
So....the total volume is
(6 yds) x (6 yds ) x (1/9 yds ) =
36 x 1/9 = 4 yds^3
So....the cost is
( 4 yds^3) x $41 per yd^3 = $ 164
