Question

7. The mass of an iron ball is 312 g. The density of
inon is 7-8 gem. Find the volume of the ball,
10 cm)
$\sqrt[ \sqrt[ { { { {x}^{2} }^{2} }^{2} }^{2} \times \frac{?}{?} ]{?} ]{?} \times \frac{?}{?}$
​

Answer 1

Explanation:

sOLUTION

Given, mass M = 312g

Density d = 7.8gcm-³

Since,d =m/v

v=m/d

Hence, Volume of an iron ball V

312/7.8

=40 cm³

Answer 2

Explanation:

the mass of iron ball = 312g

density = 7.8

therefore =

d = m/v = v= m/d

volume of iron ball v = 312 / 7.8

=40cm3
