Answer:
1 litre = 1000 cm³
Explanation:
a litre is a measure of volume
It is defined as the volume required to fill a cube with side 10 cm
the volume (V) of a cube is calculated as
V = s³ ( s is the side length )
for a cube with s = 10 cm , then
V = 10³ = 10 × 10 × 10 = 100 × 10 = 1000 cm³ = 1 litre
