Answer:
[tex]0.6366 g/cm^3[/tex] is the density of the cubic plastic.
Explanation:
Mass of the cubic block= m = 1.1 g
Volume of the cubic block = V
Volume of the cube = [tex]a^3[/tex]
a = side length = [tex]1.2\times 10^{-5} km = 1.2 cm[/tex]
1 km = 100,000 cm
Volume of cubic block = [tex]V=(12 cm)^3=1.728 cm^3[/tex]
Density of the solid block,d = ?
[tex]Density=\frac{Mass}{Volume}[/tex]
[tex]d=\frac{m}{V}=\frac{1.1 g}{1.728 cm^3}=0.6366 g/cm^3[/tex]
[tex]0.6366 g/cm^3[/tex] is the density of the cubic plastic.
