If the mass of a material is 40 grams and the volume of the material is 9 cm^3, what would the density of the material be?

Mass = m = 40 grams

Volume = V = 9 cm³

Density = d = ?

Density is defined as the ratio of mass and volume.

So,

d = m/V

Using the values, we get

d = 40/9 = 4.44 g/cm³

This means the density of material would be 4.44 g/cm³
