Answer 1

Answer:

The S.I. unit of mass is kilogram and of volume is cubic metre. Therefore the S.I unit of density is kg/m^3m

3

The C.G.S. the unit of mass is gram and of volume is cubic centimetre. Therefore the C.G.S. unit of g/cm^3m

3

Relationship between kg/m^3m

3

and g/cm^3m

3

1 kg = 1000 g or 1\ g\ =\ \frac{1}{1000}kg1 g =

1000

1

kg

And, 1\ m^3=\left(100cm\right)^31 m

3

=(100cm)

3

= 100\ cm\ \times100\ cm\ \times100\ cm\ =\ 10,00,000\ cm^3100 cm ×100 cm ×100 cm = 10,00,000 cm

Answer 2

Therefore, this particular cube has a side 5 cm. Second- You use the Density Formula i.e Density= Mass/Volume. This particular cube has a mass of 250 grams. D=2 gram/cm³.
