Question

the density of iron is7.8 gm/cm cube . ecplain the statement​

Answer 1

Answer:

First, I think you mean “iron is 7.8 g/cm^3”. You’re missing the ^3 (cubic) part.

Density is a measure of how much stuff exists in a space. An area like a city is considered dense if there are a lot of people living in a small area.

In science, density is the measure of how much matter occupies an amount of space. Matter is measured with mass, and space is measured with volume. So, when you state that iron has a density of 7.8g/cm^3, you provide an amount of mass (7.8 grams), and you specify that it occupies one cubic centimeter.
