A room is 18 feet long, 14 feet wide , 8 feet high.
find the cost of painting the four walls with two coats of paint costing $9.50 per gallon. each gallon covers 256 ft squared want with 1 coat .

L x W x H
18 x 14 x 8
Room Perimeter
P = 2W + 2L
P = 2(14) + 2 (18)
P = 28 + 36
P = 64
Perimeter * Height
P = 64, H = 8
Area to paint = 64 * 8
A = 512 sq ft
512 sq ft/256 sq ft paint coverage = gal of paint needed
512/256 = 2 gals per coat
2 gals/coat * 2 coats = ? ttl gals needed
Gal. needed * 9.50 per/gal = Total Cost
