Legend:
300 square feet = 1 gallon

Samples:
roof length = 63ft long
roof width = 47ft wide

Formula for area of the roof:

Area of the roof = (Length of the roof) x (Width of the roof)

A= 63 ft X 47 ft
A= 2961 feet

1 gallon = 300 ft
? gallon = 2961 ft

2961 ft / 300 ft per 1 gallon = 9.87 (cancelling out feet it leaves you gallons)

Answer is 9.87 gallons
