Question

A wooden box with a dimension of 0.4 x 0.4 x 0.1 m has a mass of 2 kg. The box will be loaded by an object with a mass of 8 kg. Later on, the box will be transported to another point by water. The density of water is 1,000 kg/m^3. Find and complete with calculation progress: 1)The volume of the wooden box. 2) The total mass of the parcel 3) Find the density of the parcel (loaded wooden box). 4) Make a prediction for the loaded wooden box (will it sink or float) and explain the reason for your prediction

Answer 1

Answer:

Density of water, ρ=1000 kg m−3

According to Archimedes principle, the buoyant force acting on an object is equal to the weight of the liquid displaced. 

Volume of water displaced = 50×50×50×10−6 m3=0.125 m3

Weight of water displaced = 0.125×1000×9.8=1225 N

X=1225
