Question

If the density of water is 1gm/cm cube,then find the density in kg/m square.

Answer 1

1 g/cm^3 = 1000 kg/m^3

we know
1 gm =10^-3 kg
1 cm= 10^-2 m
so (1 cm )^3 = (10 ^-2 m)^3 = 10 ^-6 m^3

so 1 gm/(cm)^3 = 10^-3 kg / (10^-6) m^3 = 10^6 x 10^-3 kg/(m^3)
=10^3 = 1000 kg/(m^3)

so density of water in Kg/m^3 = 1000

this is the answer
