Question

How many square glazed tiles of side 8 cm
will be required to cover the walls of a room
4 m by 3 m by 2 m? If 25 tiles cost 40, find the
cost of tiling the walls of the room.​​

Answer 1

Answer:

7000 is the cost of tiling the wall of room.

Step-by-step explanation:

l=4m

b=3m

h=2m

area of tile = 8*8cm²

= 64 cm²

c. s. a of room = 2(l+b) *h

= 2(4m+3m) *2m

=14m*2m

= 28m²

hence,

we can write 28m² as 280000cm²

and tile required = 280000cm²/64cm² and we got 4375 tiles

as

value of one tile is 40/25 = 1.6

and cost of tiling = 4375 *1.6

= 7000
