Answer 1

Answer:

832 square feet of paint is needed to covet pool walls

Step-by-step 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
