Answer 1

80cm cube of iron weighs 624get calculate the density of iron

•Answer ⇒ the density of the iron cube is 1.22 kg/m³.

•Explanation ⇒ Given conditions, Mass of iron = 624 g. •Volume of the cube = side³ = 80³ ...

•Density = Mass/Volume. ∴ Density = 624/512000. ∴ •Density = 0.00122 g/cm³. ∴ Density = 1.22 kg/m³.
