long. He gets the outer surface of the tank excluding the base, covered with square tiles of
side 25 cm. Find how much he would spend for the tiles, if the cost of tiles is Rs 360 per dozen.

​

Answer 1

HELLO MATE

HERE IS YOUR ANSWER

AREA OF TANK = 6a² - a²

= 5a²

= 5 * 15

= 75m²

Area of tile = .25 * .25

= 0.0625m²

No. of tiles = 75 / 0.0625

= 750000/625

= 30000/25

= 1200.

COST OF TILING = ₹1200 * 30

= ₹ 36000.
