Answer 1

Explanation:

It is given that,

Mass of platinum bar, m = 750 g

Length of the bar, l = 5 cm

Breadth of the bar, b = 4 cm

Width of the bar, h = 1.5 cm

Volume of the bar, $V=l\times b\times h$

$V=5\times 4\times 1.5=30\ cm^3$

We need to find the density of the platinum bar. The density of any substance is given by :

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

$d=\dfrac{750\ g}{30\ cm^3}$

$d=25\ g/cm^3$

So, the density of the platinum bar $25\ g/cm^3$. Hence, this is the required solution.
