Answer 1

Step-by-step explanation:

The length of the each side of water tank =1.5m=150cm

As it is given that base is not covered with tiles so, five sides of the tank are

covered with tiles.

Therefore,

Surface area of water tank =5a

2

=5(150)

2

=112500 cm

2

Side of tile =25 cm

Area of tile =25

2

=625 cm

2

Number of tiles to cover five sides of the tank =

625

112500

=180

Now,

Cost of one dozen tiles =Rs.360

Hence, total cost of 180=

12

360

×180=Rs.5400
