Answer:
[tex]7.87*10^3kg[/tex]
Explanation:
If you are asking for how much a cubic meter of iron would weight, you need to find its density.
The density of iron taken from the periodic table is [tex]7870 kg/m^3[/tex], therefore a single cubic meter would weight 7870 kg, which written in scientific notation would be [tex]7.87*10^3kg[/tex]
