Answer:
The density of the piece of metal is 10g/cm^3
Step-by-step explanation:
We know that we can write the density as:
Density = mass/volume.
In this case, we know that the mass is equal to 40g, and we know that the volume is equal to 4 cm^3
Then we can just replace these values in the above equation to calculate the density, this is:
Density = 40g/4cm^3 = 10 g/cm^3
Then the density of the piece of metal is 10g/cm^3
