Our classroom is 10 meters long, 6 meters wide, and 3 meters high. To paint the roof and four walls, we use 1.5 kilograms of paint per square meter, deducting the area of 22 square meters for doors and windows. Considering the waste of actual painting, we need to prepare more ( 1/10), how many kilograms of paint should be prepared actually?
