Question

Aluminium has a density of 2900 kg/mº. A construction company

need four cubic metres of aluminium.
Calculate the mass of the aluminium needed.

Answer 1

11600kg

Explanation:

Given parameters:

Density of aluminium = 2900kg/m³

Volume needed = 4m³

Unknown:

Mass of the aluminum needed = ?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

Density =
`(mass)/(volume)`

Mass = density x volume

Now, insert the parameters and solve;

Mass = 2900 x 4 = 11600kg
