Density = mass / volume.

 

First you need to find the volume of the cube block, which is V = s3.

v = (3)3 = 27

 

density = 27cm/27g

density = 1

A slight correction (same answer) 

Density = mass / volume     (not volume/mass)

 

volume = 27 cm^3    Mass = 27 g      density = 27 g / 27 cm^3 =  1 gm/cm^3     (MUST include units to be correct)
