a swimming pool is 18 meters long 14 meters wide and 5 meters deep. before it can be filled with water, it needs to be coated with water resistant paint.
- how many square meters of paint are needed to cover the pool?

- if water resistant paint needed for the pool cost $7.50 per square meter, how much would it cost to paint the pool

Respuesta :

surface area with no top

SA=2H(L+W)+LW


L=18
W=14
H=5

SA=2(5)(18+14)+(18)(14)
SA=10(32)+252
SA=320+252
SA=572 squaer meters

7.5 times of that
