Step-by-step explanation:
In order to find the density 1st find the volume and
divided the mass by volum then answer by g/cm^3 unit .
- p=m/v ; p=dencity , m = mass and v = volum
- V= s^3 .... for cube
so by using thos formula solve p
V= (3cm)^3
= 27cm^3
p= 216g/27cm^3
=8 g/cm^3
so the density is 8 g/cm^3
