The mass of a cast iron slab with a volume of 4m3 is 6000 kg. What is the density of cast iron?

The mass of the slab (m) is 6000 kg, and the volume (V) is 4 m3.

To find the density of cast iron, you need to divide the mass of the slab by its volume (ρ = m / V).

The units of measurement of mass and volume have already been converted to system units (SI – international system), so let’s go straight to the calculations.

ρ = 6000 kg / 4 m3 = 1500 kg / m3.

Answer: the density of cast iron is 1500 kg / m3.
