Answer: The density is 20 g/ml

Step-by-step explanation:

Density is defined as the mass contained by a substance per unit volume.

To calculate the density, we use the equation:


\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

Mass of box = 400 g

Volume of box = 20 mL

Putting values in above equation, we get:


\text{Density of box}=(400g)/(20mL)\\\\\text{Density of box}=20g/ml

Thus the density is 20 g/ml
