Question

The mass of object is200 gram and volume is 25 cm ^3 and find its density in kg /m cube

Answer 1

m= 200g = 0.2kg
$v = 25 {cm}^{3} = 25 \times {10}^{ - 6} {m}^{3}$
$density = \frac{m}{v}$
$= \frac{0.2}{25 \times {10}^{ - 6} }$
$0.008 \times {10}^{6}$
$8 \times {10}^{3} kg \: per \: {m}^{3}$
