Wall formwork measurements...

In order to obtain the most accurate measurements for our concrete tomorrow we measured the wall very accurately. My measurements show we have 185 feet 11 inches (56.6 meters). So I rounded it up to 186 feet (56.69 meters). When you multiply that with 3 foot 5 inches and then 8 inches you get the cubic yards. The final number comes to 15.69 yards of concrete. So we have ordered 16 yards for tomorrow's pour.
