Question 821349
You want to build a sidewalk at your house, 2 feet wide by 47 feet long, by 5 inches deep. Concrete costs $ 109 per cubic yard, and you need to order 15% extra. How much will your sidewalk cost?
Volume: 2*47*5/12 = 39.1667 cu ft
----
Volume = 39.1667/27 = 1.4506 cu yd.
-------
Cost = 1.15*1.4506*109 = $181.83
