A block with a volume of 12 cm3 has a density of 3 g/cm3. The block is cut into two pieces. One piece has a volume of 8 cm3, and the other piece has a volume of 4 cm3. What are the densities of the two pieces?
The density of the material DOES NOT CHANGE when the block is cut into pieces:
density = m/v
= 3 gm/cm3
