Question

find the volume of the following materials.

5 g iron 1 ton sand 165 g copper 750 g silver

Answer 1

Volume of iron : $Volume = 0.635cm^3$

Volume of sand : $Volume = 5,56,214cm^3$

Volume of copper : $Volume = 18.41cm^3$

Volume of silver : $Volume = 71.49cm^3$

Step-by-step explanation:

We know that ,  Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.

Density of iron is : 7.874 g/cm³

⇒ $Density = \frac{mass}{volume}$

⇒ $Volume = \frac{mass}{Density}$

⇒ $Volume = \frac{5}{7.874}$

⇒ $Volume = 0.635cm^3$

Density of sand is : 1.631 kg/cm³

⇒ $Density = \frac{mass}{volume}$

⇒ $Volume = \frac{mass}{Density}$

⇒ $Volume = \frac{1 ton}{1.631} = \frac{907185}{1.631}$

⇒ $Volume = 5,56,214cm^3$

Density of copper is : 8.96 g/cm³

⇒ $Density = \frac{mass}{volume}$

⇒ $Volume = \frac{mass}{Density}$

⇒ $Volume = \frac{165}{8.96}$

⇒ $Volume = 18.41cm^3$

Density of silver : 10.49 g/cm³

⇒ $Density = \frac{mass}{volume}$

⇒ $Volume = \frac{mass}{Density}$

⇒ $Volume = \frac{750}{10.49}$

⇒ $Volume = 71.49cm^3$
