Question

3. Calculate the volume of wood of mass 400kg when the density of wood is 800 kgm-3 .​

Answer 1

Given:

• Mass (m) = 400 kg
• Density (d) = 800 kg/m³

To Find:

• Calculate the Volume ?

Formula Used:

$\\ \bullet{\boxed{\sf\green{ Density = \dfrac{Mass}{Volume} }}}$

Solution:

We can Find Volume by using this Formula;

$\\ {\sf{ Density = \dfrac{Mass}{Volume} }} \\ \\ \implies{\sf{ 800 = \dfrac{400}{v} }} \\ \\ \implies{\sf{ v = \dfrac{400}{800} }} \\ \\ \implies{\boxed{\sf\large\orange{ v = 0.5 \: m^3}}}$

Hence,

The volume of the wood is 0.5 m³.
