A steel ball has a volume of 1500cm3. the density of the ball is 95g/cm3. work out the mass of the ball in kg

We can calculate the mass of the ball.

density=mass / volume ⇒ mass=density x volume

mass=95 g / cm³ * 1500 cm³=142500 g

Now we express this volume at Kg.

1 Kg=1000 g

142500 g = 142500 g * (1 kg/1000 g) = 142.5 Kg.

Answer: 142.5 Kg.
