Question

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

Answer 1

Answer:

2.71 × 10³ kg/m³

Explanation:

The density (mass/volume) of aluminum is 5.26 slug/ft³.

• The SI unit of mass is the kilogram and 1 slug = 14.59 kg

• The SI unit of volume is the m³ and 1 m³ = 35.31 ft³

We can find the density of aluminum in SI units using conversion fractions.

$\frac{5.26slug}{ft^{3} } .\frac{14.59kg}{1slug} .\frac{35.31ft^{3}}{1m^{3} } =2.71 \times 10^{3} kg/m^{3}$
