Answer:
220g/cm³
Explanation:
Given parameters: 
 Mass of the weight = 220000g 
 Volume = 1000cm³
Unknown:
Density of weight = ? 
Solution: 
Density is the mass per unit volume of a substance. 
Mass is the amount of matter in a substance. 
Volume is the amount of space a substance occupies
 Density = 

Input the parameters and solve
 Density = 
 = 220g/cm³
