Explanation:
Density = mass/volume
We are given a mass (which I am assuming is in kilograms) and a volume. Divide to find density.
Density of Saturn = 5.69 x 10²ⶠkg / 8.01 x 10²³ m³
Density of Saturn = 710. kg / m³
The density of water is 1000 kg/m³, which is higher than the density of Saturn. Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.
