School Foundations

How much concrete do you think there is in the new year 6 building foundations ?

We found out that the new year 6 building is going to be 10.6m wide and 18m long. If the foundation is going to be 0.75m thick. The volume of concrete will be 143.1m3.

They actually used 72m3 as they put lots of metal and brick work in the foundation.

The number of trucks used for this was 11. And each truck carried 6.7m3 which converted into tonnes is 13.4 tonnes (per truck).
