The density of the two smaller pieces is now : B. the same as the original density.
Further explanation
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
Volume 10 cm³ and mass of 75 g,
V=10 cm³
m=75 g
the density :
[tex]\tt \rho=\dfrac{75}{10}=7.5~cm^3[/tex]
when cut in half⇒ cutting both the mass and volume in half too
[tex]\tt \rho=\dfrac{75/2}{10/2}=7.5~g/cm^3[/tex]
