Question

Pls answer this question this urgent Hameed has built a cubical water tankk with the lid for his house with each outrr edge 1.5 m long. He gets the outer surface of the tank excluding the base covered with square tiles of sides 25 cm.Find how much he would spend for the tiles, if the cost of tiles is a ₹360 per dozen ​

Answer 1

Answer:

5400

Step-by-step explanation:

Edge of tank = 1.5 m = 150 cm

Area of five faces of the tank = 5a²

= 5 * (150)²

= 112500 cm²

Area of a square tile = 25 cm * 25 cm = 625 cm²

Number of tiles required = Area of five walls/Area of a tile

                                         = 112500/625

                                         = 180 dozen

Now,

Given, Cost of one dozen of tiles = 360

∴ Cost of 180 tiles = (360/12) * 180

                              = 5400

Therefore,

Amount he would spend = 5400

Hope it helps!
