Step-by-step explanation:
Given
[tex]1\ can = 2.2m^2[/tex]
Required
Determine the number of cans for the wall
The dimension of the wall is not given. So, I will use the following assumed values:
[tex]Length=20m[/tex]
[tex]Width = 44m[/tex]
First, calculate the area of the wall
[tex]Area = Length * Width[/tex]
[tex]Area = 20m * 44m[/tex]
[tex]Area = 880m^2[/tex]
If [tex]1\ can = 2.2m^2[/tex]
Then [tex]x = 880m^2[/tex]
Cross Multiply:
[tex]x * 2.2m^2 = 1 * 880m^2[/tex]
[tex]x * 2.2m^2 = 880m^2[/tex]
[tex]x * 2.2 = 880[/tex]
Make x the subject
[tex]x = \frac{880}{2.2}[/tex]
[tex]x = 400[/tex]
400 cans using the assume dimensions.
So, all you need to to is, get the original values and follow the same steps
