A litre is a cubic measure (with 3 dimensions), so a "cubic litre" would have 9 dimensions. Most people have difficulty with with 4 dimensions let alone 9, so I doubt that is what you mean.
Do you perhaps mean: How many litres in 1 cubic metre?
1 cubic metre = 1000 litres
1 litre = 1000 cubic centimetres.
cubic centimetres are abbreviated to cm3, cu cm or cc.
So 1 litre = 1000 cm3
= 1000 cu cm
= 1000 cc.
