Asked by Jen
what's the density of a box whose weight is 1648 newtons and whose volume is 2.8 cubic meters? Will it float in a liquid whose density is 600 kilograms per cubic meter?

Mass = Weight/g = 1678/9.8 = 171.22 kg.
Density ρ = m/V =171.22/2.8 =61.2 kg/m³.
The body is floating if
the buoyant force F acting on is greater than its weight
F =ρ1•V•g = 600•2.6•9.8 =15288 N.
F > Weight => the body will float
