# Concrete can be purchased by the cubic yard. how much will it cost to pour a slab 12 feet by 12 feet by 9 inches for a patio if the concrete costs .00 per cubic yard? since the final price is per cubic yard, i might convert everthing to yards from the beginning.

## Answers

For this case, the first thing we must do is calculate the volume of the slab.  We have then:  V = (12) * (12) * (9 * (1/12))  V = 108 feet ^ 3  Making the conversion to cubic yards we have:  V = 108 * (1/3) ^ 3  V = 4 yd ^ 3  Then, the cost of concrete is given by:  C = (4) * (54)  C = 216 $Answer: The total cost of the concrete is: C = 216$

The answer is \$216.00. Have a good day!
