Sara and Andy are painting the four walls of a rectangular room (they are not painting the ceiling or the floor). The decide to split up the work of measuring the room.Sara measures the walls. After she measures the first two walls, she finds that the first wall is 16.25 feet long, and that the second wall is 12.3 feet long. Andy measures the room's height as 244 centimeters.

If a gallon of paint covers 350 square feet, how many one gallon buckets of paint will they need to paint the room? (You can ignore openings for doors and windows in your calculations, and assume only one coat of paint is needed.)

Convert 244 cm to feet  = 8.00 ft

 

two walls at  16.25   x 8 ft     =   2  X   16.25   x  8  = 264 sq ft

two walls at   12.3    x 8 ft     =   2  x     12.3    x  8  = 196.8 sq ft       total = 460.8 sq ft

 

Amount of paint needed     460.8 ft/  350 ft/ gal  = ........ gallons
