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

I believe it is $164

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

Tysm this really helped!!

Good job, RP!!!
