<u>Answer:</u> The volume of iron is $3.031\times 10^{-3}m^3$

<u>Explanation:</u>

To calculate volume of a substance, we use the equation:

$\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$

We are given:

Mass of iron = 52.6 lbm = 23.86 kg (Conversion factor: 1 kg = 2.205 lbm)

Density of iron = $7873kg/m^3$

Putting values in above equation, we get:

$7873kg/m^3=\frac{23.86kg}{\text{Volume of iron}}\\\\\text{Volume of iron}=3.031\times 10^{-3}m^3$

Hence, the volume of iron is $3.031\times 10^{-3}m^3$
