Explanation:

Given

<u>Dimension</u>

Length= 8m

Breadth = 6m

Height = 4m

Cost per m^2 = 0.04

Required

Determine the total cost to paint 4 walls

First, we need to calculate the area of the 4 walls.

Area = 2*(Length * Height) + 2 *(Breadth * Height)

Substitute values for Length, Breadth and Height

Area = 2*(8m* 4m) + 2 *(6m* 4m)

Area = 2*(32m^2) + 2 *(24m^2)

Area = 64m^2 + 48m^2

Area = 112m^2

Cost per m^2 = 0.04.

Cost\ of\ 112m^2 = 112 * 0.04
