What is the volume of an inflatable raft if the mass of the raft with people is 300 kg

What is the volume of an inflatable raft if the mass of the raft with people is 300 kg, and the raft floats, completely immersed in the water?

Initial data: m (weight of the raft with people) = 300 kg.

Reference values: ρ (water density) = 1000 kg / m3; g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2.

Since the raft with people floats, completely immersed in the water, then the equality will be true: Fт = Fa; m * g = ρ * g * V, whence V = m / ρ.

Let’s make a calculation: V = 300/1000 = 0.3 m3.

Answer: The volume of the inflatable raft is 0.3 m3.
