Answer: 60cm^3
Step-by-step explanation:
Here we can use the relationship:
Density = mass/volume.
We know that density = 5g/cm^3 and mass = 50g, then we have:
5g/cm^3 = 50g/V
V = 50g/5g/cm^3 = 10cm^3
Then, when we introduce it in a cylinder with 50cm^3 of water, this is heavier than water (the density of the water is 1g/cm^3) it will sink, and the complete volume will be equal to the volume of the water plus the volume of the object:
Total Volume = 50cm^3 + 10cm^3 = 60cm^3
