Question

A wooden block has a mass of 562 g and a volume of 72 cm3. What is the density?

Answer 1

Answer:

Density of the wooden block is $7805.5\ kg/m^3$          

Explanation:

It is given that,

Mass of the wooden block, m = 562 g = 0.562 kg

Volume of the block, $V=72\ cm^3=7.2\times 10^{-5}\ m^3$

We need to find the density of the block. Mass per unit volume of an object is called its density. It is given by :

$d=\dfrac{m}{V}$

$d=\dfrac{0.562\ kg}{7.2\times 10^{-5}\ m^3}$

$d=7805.5\ kg/m^3$

So, the density of the wooden block is $7805.5\ kg/m^3$. Hence, this is the required solution.

Answer 2

Mass/volume is density so it’s 562g/72cm^3 so it’s roughly 7.805g per cubic centimeter
