A steel 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
mixer [17]

The equation for density is:


D=\frac{m}{V}


where the mass is in grams and the volume is in cm^{3}.


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:


4,000*1,000=4,000,000g


We are also given 0.5 m^{3}, and we need to convert to cm^{3}. 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: 100^{3}=1,000,000cm. So now we know that there are 1,000,000 cm^{3} in 1 m^{3}. We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:


1,000,000*0.5=500,000cm^{3}


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


D=\frac{4,000,000g}{500,000cm^{3}}


D=\frac{8g}{cm^{3}}


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