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`

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 = (mass)/(volume)`

⇒
`Volume = (mass)/(Density)`

⇒
`Volume = (5)/(7.874)`

⇒
`Volume = 0.635cm^3`

Density of sand is : 1.631 kg/cm³

⇒
`Density = (mass)/(volume)`

⇒
`Volume = (mass)/(Density)`

⇒
`Volume = (1 ton)/(1.631) = (907185)/(1.631)`

⇒
`Volume = 5,56,214cm^3`

Density of copper is : 8.96 g/cm³

⇒
`Density = (mass)/(volume)`

⇒
`Volume = (mass)/(Density)`

⇒
`Volume = (165)/(8.96)`

⇒
`Volume = 18.41cm^3`

Density of silver : 10.49 g/cm³

⇒
`Density = (mass)/(volume)`

⇒
`Volume = (mass)/(Density)`

⇒
`Volume = (750)/(10.49)`

⇒
`Volume = 71.49cm^3`
