Question

If 1 litre of water weighs 1 kg, then how many cubic millimetres of water will weigh 0.1 gm?

(a) 1

(b) 10

(c) 100

(d) 1000

Answer 1

Correct option is (c) 100

1 Kg = 1000 gm = 1 litre

\(\therefore\) 0.1 gm = 1 x 10^-4 litre = 1 x 10^-1 cubic meter

= 1 x 10^-1 x 1000 cubic millimeter

= 100 cubic millimeter.
