An object has a mass of 48g and it has a height of 5cm, a width of 2cm and a length of 5cm.

0.96g/cm³

Explanation:

Given parameters:

Mass of the object  = 48g

Height of the object  = 5cm

Width of the object  = 2cm

Length of the object = 5cm

Unknown:

Density = ?

Solution:

Density of a body is the mass per unit volume of the body.

  Mass is the amount of matter in a substance

  Volume is the space such a body occupies

To find the volume;

     Volume  = l x w x h

 Insert the parameters and solve;

    Volume = 5cm x 2cm x 5cm = 50cm³

  Density  =

Density =   = 0.96g/cm³
