Answer:
[tex]Cost\ of\ 112m^2 = 4.48[/tex]
Explanation:
Given
Dimension
[tex]Length= 8m[/tex]
[tex]Breadth = 6m[/tex]
[tex]Height = 4m[/tex]
Cost per [tex]m^2[/tex] = 0.04
Required
Determine the total cost to paint 4 walls
First, we need to calculate the area of the 4 walls.
[tex]Area = 2*(Length * Height) + 2 *(Breadth * Height)[/tex]
Substitute values for Length, Breadth and Height
[tex]Area = 2*(8m* 4m) + 2 *(6m* 4m)[/tex]
[tex]Area = 2*(32m^2) + 2 *(24m^2)[/tex]
[tex]Area = 64m^2 + 48m^2[/tex]
[tex]Area = 112m^2[/tex]
Cost per [tex]m^2[/tex] = 0.04.
[tex]Cost\ of\ 112m^2 = 112 * 0.04[/tex]
[tex]Cost\ of\ 112m^2 = 4.48[/tex]
