Question

A block of metal has a width of 3.2 cm, a length of 17.1 cm, and height of 4.2 cm . Its mass is 1.2 kg . Calculate the density of the metal. Express your answer to two significant flgures and include the appropriate units.

Answer 1

Step-by-step explanation:

V = volume (cm³)

D = density (kg/cm³)

V = 3.2 × 17.1 × 4.2

V = 229.824

D = 1.2/229.824

D = 0.0052213868

D = 0.0052 kg/cm³ or, equally, 5.2 g/cm³
