I would like to make a small concrete slab of the following dimensions.
Length: 1.2m Width: 0.86m Depth: 0.09m
The cubic volume as i understand it is all those numbers multiplied.
If a bag of pre-mix concrete says
0.2m2 x 50mm
How many bags would I need?
Update: Brick BBQ construction. I am doing this for "homework" :)
