Answer:
The density of cube is 6.17959 
Step-by-step explanation:
The density is given by ration of a mass of body and volume occupied by a body.

Where, 
 is density.
 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
=0.148877
Now, the Density of the cube will be 



Thus, The density of cube is 6.17959
