Note that:

  • Density =
    (mass)/(volume)
  • Specific gravity =
    (Density_(object) )/(Density_(water) )

Givens

  • dimensions of object
  • mass of object

Solving

To find density, you need volume.

Volume

Volume = length * width * height

Volume = 4.5 cm * 4.2 cm * 4.0 cm

Volume = 76 cm³

Density

Density =
(371 g)/(76cm^(3) )

Density = 4.9 g/cm³

Specific gravity

The density of water is approximately 1 g/cm³.

Specific gravity =
(4.9g/cm^(3) )/(1g/cm^(3) )

Specific gravity = 4.9

Answer:

Density: 4.9 g/cm³

Specific gravity: 4.9
