In order to solve this, we start by finding the surface area of the shed. We do this by adding up all the sides of the shed. There will be two sides that have the dimensions 8 X 9, two sides that have the dimensions 8 X 6.5, and two sides that have the dimensions 9 X 6.5
Now, we add all of these up. 2(8*9) + 2(8*6.5) + (9*6.5) = 365, so the surface area is 365 square feet. Now, figure out how many gallons of paint we will need.
We do this by dividing 365/250, which equals 1.46. So, you will need 1.46 gallons of paint to cover the shed.
