A cube has a length of 1.02 cm and a mass of .001012 kg what is its density

d = 9.5× 10⁻⁴ Kg/cm³

Explanation:

Given data:

Length of cube = 1.02 cm

Mass of cube = 0.001012 Kg

Density of cube = ?

Solution:

The length , height and width of cube is always same. Thus the volume of cube is,

Volume = length × height× width

Volume = 1.02 cm × 1.02 cm × 1.02 cm

Volume = 1.06 cm³

Density of cube:

d = 0.001012 Kg /1.06 cm³

d = 9.5× 10⁻⁴ Kg/cm³
