the mass per unit area of a type of metal sheet is 3 kg per m2 .State the rate in g per 100 cm2​

Respuesta :

If we start with

[tex]\dfrac{3\text{ kg}}{1\text{ m}^2}[/tex]

we can convert the fraction recalling that

[tex]1\text{ kg}=1000\text{ g},\quad 1\text{ m}^2=10000\text{ cm}^2[/tex]

So, we have

[tex]\dfrac{3\text{ kg}}{1\text{ m}^2} = \dfrac{3000\text{ g}}{10000\text{ cm}^2} =\dfrac{30\text{ g}}{100\text{ cm}^2}[/tex]
