Answer:
832 square feet of paint is needed to covet pool walls
Explanation:
The correct question is
A swimming pool is 40 ft long 12 ft wide and 8 feet deep how many square feet of paint is needed to cover the walls of the pool?
To find out the area of the walls, multiply the perimeter of the base by the deep of the walls
so
![A=2(L+W)D](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jefh8zdrxnplz0cm2n0t204g9o6v6g54wd.png)
we have
![L=40\ ft\\W=12\ ft\\D=8\ ft](https://img.qammunity.org/2020/formulas/mathematics/middle-school/c0ugpqbh5ri9flb05hkr79ftz3lzwpm4gh.png)
substitute
![A=2(40+12)8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jzonix9n8lm4ch7zd923665lf4iz3hfjsn.png)
![A=832\ ft^2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/71howhhfx4h00pr6ns66efq4t27xwa0xuk.png)
therefore
832 square feet of paint is needed to covet pool walls
