The properties of a cube are listed below:

Mass = 80 g
Length of side = 2 cm

What is the density of the cube?

A.) 10 g/cm^3
B.) 20 g/cm^3
C.) 160 g/cm^3
D.) 640 g/cm^3

Respuesta :

Answer

The answer is

[tex]13.33 gcm^{-3}[/tex]

Explanation

  • Volume of the cube = ?
  • The mass of the cube = 80 g
  • The density of the cube = ?

The all the sides of the cube has same length.

If the length of one side of cube is 2 cm, the length of the width and height will also be 2 cm.

So,

[tex]Volume of cube = a^3[/tex]

as a = 2 cm

[tex]Volume = 8 cm^3[/tex]

[tex]Density = Mass/Volume[/tex]

[tex]Density = 80 g / 8 cm^3[/tex]

[tex]Density = 10 gcm^{-3}[/tex]

The density of the cube will be

[tex]10 gcm^{-3}[/tex]

The option is (A)
