volume = 2 x 1 x 3 = 6m³ = 6000000cm³
ρ= massa/volume
=60000gram/6000000cm³
=0,01gram/cm³
p = 2 m
l = 1m
t = 3m
m = 60 kg = 60.000 gram ( 1kg = 1000 gram)
Dit: ρ (dlm CGS)....?
V = p x l x t = 2m x 1m x 3m = 6m³
V = 6m³ = 6x1.000.000 cm³ = 6.000.000cm³
,
ρ = m/V
ρ = 60.000gram/6.000.000cm³
ρ = 0,01 g/cm³
