019289*10^3 g/cm^3 = 19.ρ = m/V = .827 g / (.35 cm)³ = 19.......

What is its density?

Volume of cube = (3.5)^3*10^-3 cm^3 = 42.875*10^-3 cm^3
Mass = 0.827g
density = mass/volume = 0.827/42.875*10^-3 = 0.019289*10^3 g/cm^3 = 19.3 g/cm^3

Density = mass/volume:

ρ = m/V = .827 g / (.35 cm)³ = 19.3 g/cm³
