Answer 1

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`

we have

`L=40\ ft\\W=12\ ft\\D=8\ ft`

substitute

`A=2(40+12)8`

`A=832\ ft^2`

therefore

832 square feet of paint is needed to covet pool walls
