#"Density,"# #rho=1*g*cm^-3#

#"Density"# is simply the quotient....#"Mass"/"Volume"#

And here we are quoted the mass, and for a cube we may calculate the volume straightforwardly....

And so #rho=(27*g)/(3.0*cmxx3.0*cmxx3.0*cm)=(27*g)/(3.0*cm)^3#

#1.0*g*cm^-3#....this is a dense block of wood. Would it float?
