Question

A cubical block of wood of side 0.5 m floats in water. Given that the densities of wood and water are 800 and 1000 kg/m3 respectively

Calculate the depth of the block immersed in water.

Answer 1

Depth = Dwo/Dwa * h = (800/1000) * 0.5 = 0.40 m.

Answer 2

a cube of sides 0.5 m floats in a large tank of water at a height of 0.3 m above the surface ..calculate
1. weight of the cube
2. vertical upthrust given to the cube by the water
3. volume of water displaced by the cube
