Question

the length and Length breadth and height of a room in a house are 8m 6m and 4m respectively the house on a decides to paint the four walls of the room at the cost of ,0.04 square of wall how much will the owner spend in painting the walls​

Answer 1

`Cost\ of\ 112m^2 = 4.48`

Step-by-step explanation:

Given

Dimension

`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`

`Cost\ of\ 112m^2 = 4.48`
