One gallon of paint covers 400 square feet. How many gallons are needed if Lori wants to apply 2 coats of paint to all the walls and the ceiling

Answer 1

Hi Etelvina,

 

We need to know the square feet of the walls and the ceiling to be able to answer this question. But if it is 400sq ft, then

 

1 gallong --> 400sq feet

? gallon  --> 2x(2000) feet

 

 

x  = 4000/400 = 10 gallons.

 

Hope this helps.
