Hanumappa and his wife Gangamma are busy making jaggery out of sugarcane juice. They have processed the sugarcane juice to make the molasses, which is poured into moulds in the shape of a frustum of a cone having the diameters of its two circular faces as 30 cm and 35 cm and the vertical height of the mould is 14 cm (see Fig.). If each cm3 of molasses has a mass of about 1.2 g, find the mass of the molasses that can be poured into each mould( in kg). (Take π = 227)
