Concrete has now been poured

Sorry no pics yet will get them up soon. I calculated it to 1.7 meters cubed. But when the wagon had poured it came to 2.0, suprise suprise. It came to £200. My rule is with the concrete guys is add thirty quid cos they will add it on to whatever you use. Have also took delivery of 144 concrete block, 40 trench blocks, 70 engineering brick (73mm) and 70 concrete brick (73mm), 2 tons of sand and 10 bags of cement, total £540 delivered.
