Answer:
2.14
Step-by-step explanation:
Assuming no windows or doorways, there are 2 walls that have an area of 20*8 and 2 that are 18*8. That creates a total area of:
160*2 + 144*2 = 608 square feet
The ceiling adds 20*18 = 360 square feet
Total per coat is 968 square feet.
Multiply that by 2 for 2 coats:
2*968 = 1936
Divide that by 400 and the nearest half gallon is 5.0 gallons (4.84 rounded to the nearest .5)
