Question

The density (mass//volume) of aluminum is 5.26 slug/ft3slug/ft3. Determine its density in SI units. Use an appropriate prefix.

Answer 1

density of aluminium in SI unit will be
`2712.338kg/m^3`

Step-by-step explanation:

We have given density of aluminium is 5.26
`slug/ft^3`

We have to change this unit into SI unit

Si unit of density is
`kg/m^3` as kg and
`m^3` both are SI unit

Now we know that 1 slug = 14.593 kg

And 1 cubic feet = 0.0283 cubic meter

So 5.26
`slug/ft^3` will be equal to
`5.26* (14.593kg)/(0.0283m^3)=2712.338kg/m^3`

So density of aluminium in SI unit will be
`2712.338kg/m^3`
