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

Answer:

11600kg

Step-by-step 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  = $\frac{mass}{volume}$

  Mass  = density x volume

Now, insert the parameters and solve;

  Mass = 2900 x 4  = 11600kg
