Given parameters:

Density  = 2.7g/cm³

Length of the cube  = 10cm

Unknown:

Mass of the cube = ?

Solution:

Density is the mass per unit volume of a substance.

  Density = [tex]\frac{mass}{volume}[/tex]  

                Mass = density x volume

  We need to find the volume of the cube;

    Volume of the cube  = L³

where L is the length of the cube;

         Volume of the cube = 3³ = 27cm³

So, the mass of the granite = 2.7 x 27 = 72.9g

The granite has a mass of 72.9g
