The formula to find density is Mass/Volume

We have
Density = [tex]7.8[/tex] [tex] \frac{g}{cm^{3}} [/tex]
Volume = [tex]10504 cm^{3} [/tex]

Hence
Mass = 7.8×10504 = 81931.2 gram

The mass of the iron beam is equal to 81931.2 g.

What is the Density of a Material?

The density of a material represents the ratio between the mass of this material and its respective volume. This property of material can be found from the following equation: [tex]d=\frac{mass}{volume}[/tex].

The question gives:

density of iron =7.8 g/cm³

volume=10,504 cm³

Then,

[tex]d=\frac{mass}{volume}\\ \\ 7.8=\frac{x}{10,504} \\ \\ x=10,504*7.8=81931.2 g[/tex]
