Question

Mass of a cubical copper block of 2cm side is 64g. Calculate the density of copper.

Answer 1

hope this answer helps.

Answer 2

Answer:

Density, $d=8\ g/cm^3$

Explanation:

It is given that,

Mass of the cubical copper block, m = 64 g

Side of the cubical copper block, a = 2 cm

Let d is the density of the copper. Total mass per unit volume of the object is called its density. Mathematically, it is given by :

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

V is the volume of cube, $V=a^3=(2\ cm)^3=8\ cm^3$

$d=\dfrac{64\ g}{8\ cm^3}$

$d=8\ g/cm^3$

So, the density of copper is $8\ g/cm^3$. Hence, this is the required solution.
