Problem:

If paint covers 300 square feet per gallon, how many gallons will it take to paint a home with a flat roof measuring 63 feet long, 47 feet wide, and 10 feet high?

If the paint is $17 a gallon, what will the paint cost be? (Assume no door and window areas)

Solution:

Area of walls Ft2 covered by one gallon	=	2(L x H) + 2(W x H) 300	= gallons needed
	=	2(63 x 10) + 2(47 x 10) 300	= 7.3 gallons of paint

8 gallons x $17 = $136 (must buy nearest full gallon)
