A hippo is dozing under water with only its small nostrils sticking out. It has a mass of 2500 kg and a volume of about 2.46 m3 after exhaling. The hippo is in a pool of fresh water, with a density of 1g/cm3. What is the buoyancy force on the hippo?

The buoyancy force on the hippo is 24108 N

Explanation:

Given;

mass of hippo, m = 2500 kg

volume of hippo, V = 2.46 m³

density of fresh water, ρ = 1g/cm³

The buoyancy force on the hippo, is calculated used the following formula;

density of hippo = mass / volume = 2500/2.46 = 1016.26 kg/m³

density of fluid = 1g/cm³ = 1000 kg/m³

Therefore, the buoyancy force on the hippo is 24108 N

i don't understand. explain it clearly
