Question

A piece of brass of volume 30 cm^3 and mass 27 kg. Find its density in kg/m^3​

Answer 1

Answer:

0.9 kg/m^3

Explanation:

Because density is a ratio of mass / volume and our given volume is in cm^3 so we have to convert it into m^3 to get our answer.

1cm=1//100m

therefore 30cm=1/100m

=30/100

=0.3m^3

now we have found density in m^3

so now we can apply or formula which is

density=mass/volume.

{mass =27kg and volume=0.3m^3}

27kg/0.3m^ 3 = 0.9kg/m^3
