The density is given by ration of a mass of body and volume occupied by a body.

Where,
is density.
m is mass of a body
V is the volume of a body
Given that one side of the cube is 0.53cm
Hence, the volume of a body is V=
=0.148877
Now, the Density of the cube will be



Thus, The density of cube is 6.17959 
The reciprocal means you're just flipping the fraction around,, so it would be 9/10
