Question

Find the volume of a piece of wood having mass 80 kg. The density of wood is 800 kg/ m3

Answer 1

ㅤGiven :-

Mass of the wood is 80 kg

Density of the wood is 800 kg/m³

ㅤTo find :-

Volume of the body

ㅤㅤ✠Solution :-

As we know that ,

Density is defined as mass per unit volume .

So,

Density = Mass / Volume

Substituting the values,

Let the volume of wood be v ,

800 = 80/v

10 = 1/v

10v = 1

v = 1/10

v = 0.1 m³

So, the volume of the wood is 0.1 m³
