Answer 2

Answer:

If the density of 1 kg of the metallic sphere is 2.5 g cm^-3 then the volume occupied by the spheres is​ $400 cm^{3}$

Explanation:

In the question, it is given that,

The density of the metallic sphere = $2.5\ gcm^{-3}$

Mass of the metallic sphere  = $1 kg$ = $1000g$

Let m be the mass and v be the volume of a metallic sphere, then, its density d is given by the expression,

$d = \frac{m}{v}$

Rearranging the above equation for obtaining v,      

$v=\frac{m}{d}$ ...(1)

Substitute values into equation(1)

$v=\frac{1000}{2.5} =400cm^{3}$

The volume of the metallic sphere =$400cm^{3}$
