"5.5129 g/cm³" is the appropriate solution.

Step-by-step explanation:

According to the question, the values are:

Iron's density,

= 7.874 g/cm³

Base edge length,

= 4 cm

Base edge width,

= 9 cm

Height,

= 5 cm

Mass,

= 425 g

As we know,

The Density of rectangular pyramid will be:

= $\frac{Mass}{Volume}$

or,

= $\frac{Mass}{Length\times Width\times height}$

On putting all the given values, we get

= $\frac{425}{4\times 9\times 5}$

= $\frac{425}{180}$

= $2.3611 \ g/cm^3$

hence,

The difference will be:

= 7.874-2.3611

= $5.5129 \ g/cm^3$
