Question

The density of gold is 19 300kg/m^3. what is the mass of gold cube with the length 0.2015m?

Answer 1

The mass is
`157.87m^3`

Step-by-step explanation:

Given data

length of cube= 0.2015 m

density = 19300 kg/m^3.

But the volume of cube is given as
`l*l*l= l^3`

`volume -of- cube= 0.2015*0.2015*0.2015= 0.00818 m^3`

The density is expressed as = mass/volume

`mass=19300*0.00818= 157.87m^3`
