What is the density of a cube with a mass of 4.5 killograms and measures 100cm on each side

Remember that density is mass divided by volume. first u must calculate the volume. so do 100 to the power of 3 (cause volume is width * lenth*height so u end up having to do 100 * 100*100) in your calculator. U know the mass is 4.5 kilograms. simply do 4.5 divided by 100 to the power of 3.
