Asteel bar has a mass of 4,000 kilograms and a volume of 0.5 cubic meters . calculate its density. write your answer as a whole number.

The equation for density is:

where the mass is in grams and the volume is in .

We are given 4,000 kilograms, and we know that there are 1,000 grams in 1 kilogram, so we need to multiply to convert to grams:

We are also given 0.5 , and we need to convert to . We know that there are 100 cm in 1 m, and since we are talking about cubic volume, we must also raise 100 to the 3rd power: . So now we know that there are 1,000,000 in 1 . We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:

So now that we have the correct units, let's plug them into the equation:

So now we know that the density is 8g/cubic centimeter.
