Question

A rectangular piece of wood measures 4 cm by 6 cm by 8 cm and has a mass of 20 g. What is the
density of the piece of wood?
​

Answer 1

Answer:

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....
