Question

A block of metal has a width of 3.2 cmcm, a length of 17.1 cmcm, and height of 5.0 cmcm . Its mass is 1.2 kgkg . Calculate the density of the metal. Express your answer to two significant figures and include the appropriate units.

Answer 1

≅ 4.39 gm/cm^3

Step-by-step explanation:

Given data:

width of block =3.2 cm

length = 17.1 cm

height = 5.0 cm

Mass = 1.2 kg

Therefore volume= width×length×height = 3.2×17.1×5= 273.6 cm^3

now, density = mass/volume

calculating density in gm/cm^3

= 1200/273.6 = 4.38596

≅ 4.39 gm/cm^3
