A rectangular block of copper metal weighs 1896g. The dimensions of the block are 8.4cm by 5.5cm by 4.6cm. From this data , calculate the density of copper?​

Given:
Weight of the block = 1896 g
Length of the copper box= 8.4 cm.
Breath of the copper box = 5.5 cm.
Height of the copper box= 4.6 cm.

To find:   Density of copper

Solution:
volume of the copper box  = $Lenght \times Breadth \times Height $

= $8.4 \times 5.5 \times 4.6$

= 212.52 cubic cm.  

Density of copper = $\frac{Weight \ of \ copper }{Volume \ of \ copper}$

  
So, density of copper  =  $\frac{1896}{212.52}$

= 8.92 gm/cc.

So, the density of copper is 8.92 gm/cc.
