Question

a cube of side 20cm have a mas of 16kg find it relative density​

Answer 1

Answer:

2kg/m^3

Explanation:

the density of the cube = mass / volume

20cm = .20m

volume = .008m^3

so, the density of the cube is 16/ .008 kgm^-3

=2000kg/m^3

relative density = density of water / density of water

density of water = 1000kg/m^3

relative density =2000/1000

=2kg/m^3

hope this helps :)
