The volume of concrete used per m2 of floor is calculated as follows:
For this example assume: that the floor has ribs at 900mm centres
that the mould is 225mm deep
there is 100mm of topping
i.e. total depth = 325mm
Total volume per m2 of floor = 1.0 x 1.0 x 0.325 = 0.325 m3
Void volume per m2 of floor (table opposite) = 0.143 m3
So, volume of concrete per m2 is 0.325 - 0.143 = 0.182 m3
