Question 143869
There you go, if you want 0.5 yard thick of concrete on the driveway too (just like the thickness of the driveway), multiply Length, Width, & Thickness = 18*4*0.5=36 cubic yards ------ This how much concrete you need.
And, $3.50/cu.yard * 36 cub.yards = $126 -------- cost for the concrete for the whole driveway (plus labor$$$).
Thank you,
Jojo
