Question

Mass of an iron rod is 52g.The density of iron is 7.8 cm-3.Find the volume of the rod

Answer 1

Answer:

Explanation:

As we know, D=M/V

If we prefer to cgs system then we can easily find the answer

7.8=52/x

X=7.8/52

X=0.15

But if we prefer to the SI System then we will have to convert the units,

on changing the units we obtain,

Mass=52g=0.052kg

Density=7.8 g/cm^3= 0.78kg/m^3

So, the volume which we obtain will be

=0.78/0.052

=15 m^3

Hope, it will help you
