Answer:
The box will Sink. Its density is higher
Step-by-step explanation:
Density is the property to know if an object will sink or float in this kind of exercise, as we know the density equation is:
Density= Mass/Volume, d=m/v
In this object the density will be:
D= 100g/20ml= 5g/mL
So, the density is 5g/ml and the density of water is 1g/mL.
If a body has a higher density of water will sink otherwise will float.
