What is the density in cm if an iron cube weighs kg?

To find the density of an iron cube, you would need both its mass in kilograms and its volume in cubic centimeters. Density is calculated using the formula: density = mass/volume. If you know the weight of the iron cube in kilograms and can determine its volume (for example, by measuring its dimensions), you can convert the mass to grams (1 kg = 1000 g) and then divide by the volume in cm³ to find the density in g/cm³.
