Hello there!!!!!
we know that,density= mass/volume
mass= 20 gm (given)
volume= length*breadth *height
so, volume= 4*6*8
= 192cm³
therefore, density= 20/192
= 0.104
since its density is less than the density of water.
Therefore it'll float on water....

Given:
Dimensions of the wood = 4 cm by 6 cm by 8 cm
Mass of the wood = 20g
To Find:
Density of the piece of wood and if it will float.
Solution:
Using the formula of density -
Density = Mass/Volume
Substituting the values -
Density = 20 / 4 × 6 × 8
D = 20 / 192
D = 0.104
Answer: Density of the piece of wood is 0.104g/cm³. Because its density is lower than that of water. As a result, it will float on water.
