A wooden bookshelf has external dimensions as follows: Height = 110 cm, Depth = 25 cm, Breadth = 85 cm. The thickness of the plank is 5 cm everywhere. The external faces are to be polished

A wooden bookshelf has external dimensions as follows: Height = 110 cm, Depth = 25 cm, Breadth = 85 cm (see Fig. 13.31). The thickness of the plank is 5 cm everywhere. The external faces are to be polished and the inner faces are to be painted. If the rate of polishing is 20 paise per cm^2 and the rate of painting is 10 paise per cm^2, find the total expenses required for polishing and painting the surface of the bookshelf. We have found that the total expense required for polishing and painting the surface of the bookshelf is ₹ 6275.
It is given that the wooden bookshelf has external dimensions as follows: Height = 110 cm, Depth = 25 cm, Breadth = 85 cm with the thickness of the plank as 5 cm everywhere. If the external faces are to be polished and the inner faces are to be painted given the rate of polishing is 20 paise per cm² and the rate of painting is 10 paise per cm², we have found that the total expense required for polishing and painting the surface of the bookshelf is ₹ 6275.
