It takes 1.5 litres of sugar soap to wash a square meter of ceiling and 0.5 litres of sugar soap to wash a square meter of wall. Bianca's room is 4 metres
high and each wall is 5 metres wide. There is one window, which is 4 square metre and a door, which is 9 square meter. How much sugar soap will Bianca need, assuming she does not wash the door or window has ( a room has four walls and a roof)?
