WHAT IS DENSITY OF MATERIAL? Explanation of phycial material

1. Density (ρ)

Mass per unit volume of homogeneous 

material (without counting voids)

.  ρ = M / V

          Where M = Mass and V= Volume

•Density of some building materials is as 

Brick	2.5–2.8	2500-2800
Granite	2.6–2.9	2600-2900
Portland cement	2.9–3.1	2900-3100
Wood	1.5–1.6	1500-1600
Steel	7.8–7.9	7800-7900
