Ok, I'm getting all confused about how many bags of cement I will need to make a small slab 1.6m x 1.6m x 0.1m (0.256 cubic meters).

One place I looked says I will need like 20 bags but i've made conrete in the past and im sure I never used that much. I would most likely go the 1:2:3 ration of cement, sand, aggregate and maybe a layer of re-mesh to make it sturdy. I have a feeling that 3 bags would cover this.

Can anyone help out please?
