[Owen11]

I’m going to be building a out building
9 meters long 4.2 meters at the front it will be a triangle shape 200mm deep 100mm type1 & 100mm off reinforced concrete.
Can some one help me work out how much of each I need please

Bizarre description aside, any chance you could post a diagram please?

Plenty of online calculators - just insert volumes to be filled.

If you just measn for the base then 2 cu. metres of concrete and same for sub base. Your footings will depend on the size of them.
