The mass of a cast iron slab with a volume of 4m ^ 3 is 6000 kg, what is the density of cast iron.

As we know from the school physics course, the density of a substance can be calculated using the following formula:

p = m: V, where m is the mass of the selected substance, and V is, respectively, the volume of the selected substance.

Let us determine what density the cast iron has, when from the condition of the task we know that a plate made of it with a volume of 4 m3 has a mass of 6000 kilograms:

6000: 4 = 1500.

Answer: With such initial data, the density of cast iron is equal to 1500 kg / m3.
