what is the volume, in millilitres, of water in the container

Question

450ml, 70cl, 0.75l, 2l are poured in a 6 litre container

Answer 1

Convert all to milliliters and add them up.

450 ml = 450 ml

70 cl x 10 ml/cl = 700 ml

0.75 l x 1000 ml/l = 750 ml

2 l x 1000 ml/l = 2000 ml

Add them up to get the total volume.
