The relativ density of steel is 7.8

A. Find the mass of solid steal cube of side 10cm
B. What volum of steel has amass of 8kg

density (g/cm^3) = mass(g) / volume(cm^3)

so ...

The relative density of steel is 7.8, meaning that it is 7.8 times denser than water. This has practical implications when it comes to calculating the mass and volume of steel objects. For example, if we have a solid steel cube with a side length of 10 cm, we can find the mass by multiplying the volume by the density. To calculate the volume, we use the formula V = (side length)^3, giving us V = (10 cm)^3 = 1000 cm^3. Multiplying the volume by the density, we find the mass to be 1000 cm^3 * 7.8 g/cm^3 = 7800 g (or 7.8 kg). On the other hand, if we are given a mass of 8 kg and want to determine the volume of steel that corresponds to this mass, we can use the inverse of the density. Dividing the mass by the density (8 kg / 7.8 g/cm^3), we find that the volume of steel associated with this mass is approximately 1.03 cubic meters. This showcases the relationship between mass, volume, and density in the fascinating world of steel.
