Answer 1

Answer:

ans of 1st

Explanation:

Although the SI unit of volume is the cubic metre (m3), the volume of a liquid is usually expressed in terms of litres (or submultiples of a litre). A litre has the same volume as a cubic decimeter (a decimeter is one tenth of a metre). A cubic metre of a liquid is thus equivalent to one thousand litres (1000 L).
