Answer 1

Rs 4320 is spent for the tiles to cover the outer surface of the tank excluding the base  with square tiles of side 25 cm

Step-by-step explanation:

Hameed has built a cubical water tank with lid for his house, with each other edge 1.5 m long.

the outer surface of the tank excluding the base, covered with square tiles of side 25 cm

and top is lid

hence Surface area to be covered with tiles = 4 * 1.5²  m²

1m = 100 cm

= 4 * 150 * 150

Tile size = 25 cm * 25 cm

Number of tiles required =  4 * 150 * 150 /( 25 * 25)

= 4 * 6 * 6

= 144

= 12 * 12

= 12 Dozen tiles

Cost of tile  = Rs 360 per Dozen

Cost of 12 Dozen  = 12 * 360

= Rs 4320

Rs 4320 is spent for the tiles to cover the outer surface of the tank excluding the base  with square tiles of side 25 cm
