Question

The relative density of oak wood is 0.64 what is its density in



a. The si system and



b. The cgs system?

Answer 1

Answer: Density in CGS system

= RD* 1 g/cm^3

=(0.64*1) g/cm^3

=0.64 g/cm^3 (Ans.)

Density in SI system =RD* 1000 kg/m^3

=0.64* 1000 kg/m^3

=(0.64*1000) kg/m^3

=640 kg/m^3 (Ans.)

Explanation:

Answer 2

Given:

Relative density of oak wood is 0.64

To Find:

its density in

a. si system

b. cgs system

Solution:

We know that,

Relative density (RD) = 0.64

So,

Density in SI system = RD x 1000 kg/$m^{3}$ = 0.64 x 1000 kg/$m^{3}$ = 640 kg/$m^{3}$

Density in CGS system = RD x 1 g/$cm^{3}$ = (0.64 x 1) g/$cm^{3}$ = 0.64 g/$cm^{3}$

Hence, the density of oak wood in the SI system is 640 kg/$m^{3}$ and in CGS system is 0.64 g/$cm^{3}$ .
