Sol. Ans.(c).

Given 1 litre = 1 kg.

We know that 1 m³ (1 cubic metre) is exactly 1000 Litres.

=>1000 litre = 109 cubic millimetres.

(How? 1 m x 1 m x 1 m = 100 cm x 100 cm x 100 cm = 1000 mm x 1000 mm x 1000 mm = 10⁹ mm³)

=>1 litre = 10⁶ cubic millimetres = 1 kg = 1000 gm

So 0.1 gram = 10² mm³ = 100 cubic millimetres.
