Question

20. If weight of 1 m³ of a metal be 4060 kg. 3 What will be the weight of 1 cm³ of the same metal?​

Answer 1

Step-by-step explanation:

If you know the term density then you might be able to understand this answer. Let me help you out with density first.

Density=

mass/volume

So density = mass per volume.

* Density of the given metal is it's mass per volume in SI SYSTEM which is 4060 kg m-3 or 4060 kg/m3.

To get the weight of 1cm3 of that metal, 4060 kg/m3 must be converted to CGS System. Where unit of mass is gram and unit of volume is cm3.

* To convert kg/m3 to g/cm3, the formula is division by 1000

$\frac{4060}{1} \div 1000 = \frac{4060}{1000} = 4.06$

So we finally get 4.06g/cm3

The weight of the metal will be 4.06g for 1cm3 of volume.
