Concrete consumption

[Gogol]

Hi,
I am going to cast a slab that is 4100X1200X120mm and have bought coarse concrete that gives 13L per bag, but unfortunately, I'm stuck in figuring out how many bags I need. I have 6x 25kg bags lying around but that feels too little.

You need 39 more bags (39.4 to be exact).

One liter = one cubic decimeter.
Your volume would then be 41 x 12 x 1.2 = 590 liters. If each sack provides 13 liters of concrete, it would take almost 46 sacks

46 is correct! not 39 so you need to buy quite a bit more..

Thank you for the quick responses have a nice evening!

39 more bags, it actually says.

39 bags to go, that's what it actually says.

I'm not so lively that late in the evening. I shouldn't write anything after 8:00 PM.
