Our classroom is 12 meters long, 8 meters wide, and 4 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. For paint (1/10), how many kilograms of paint should be prepared to paint this classroom?
