Answer:

So we need about 2 gallons

Step-by-step explanation:

The lateral surface area is found by

LSA = Perimeter * height

      = 2*(l+w) * h

The length is 12   the width is 15 and the height is 9

       = 2(12+15) * 9

        = 2* (27) * 9

         = 486 ft^2

If each gallon covers 250 ft^2

Take 486/250

1.944 gallons of paint are needed.

We need to buy the paint in gallons

So we need about 2 gallons
