Calculate the area of ​​paint Formula one: Total brushing area converted from floor area Algorithm: Total paint area = four walls painted + ceiling paint Four-sided wall painting area = floor area multiplied by 2.5 Ceiling painting area = floor area Therefore, the total painted area (including ceilings) = floor area times 3.5 (note: due to ceiling height and the number of doors and windows have increased or decreased) Formula 2: Estimated paint volume for repainted walls = total painted area divided by unit area painted For example, if the area to be painted is 10 square meters, the total painting area is 35 square meters, then the estimated amount of paint on the repainted wall is: 35 square meters divided by 3.5 (3.5 square meters per kilogram)=10. Therefore, the required paint weight is 10 kg. (Note: The actual amount of paint will increase or decrease depending on the condition of the wall and the method of painting.)
