Answer:
3 gallons of paint
Step-by-step explanation:
Painting with a coat of paint
Area of the building painted = Area of Rectangle with dimensions 20 ft × 10 ft + Area of triangle with height 5 ft and base 20 ft + Area of rectangle with dimensions 24 ft and 10 ft
= {20 × 10} + {(1/2)×5×20} + {24×10}
= 200 + 50 + 240
= 490 square ft
With two coats of paint:
Multiply Area of the building painted by 2
= 2 × 490 square ft
= 980 square ft.
Area of the building painted = 980 square feet.
Paint needed to cover 350 square feet = 1 gallon of paint
980 square feet needs
= 980/350
=2.8 gallons of paint.
Approximately, 3 gallons of paint to the nearest gallon
