Answer:
ANSWER
We have,
Given that,
The length of the tile=10cm.
The base of tile=4cm.
We know that,
Area=l×b
10×4
=40cm2
Given that,
Total number of tiles in the room =1000
Therefore,
The total area of the floor
=1000×40
=40000cm2
Given that,
Cost of polishing per cm2=9.50/cm
Therefore,
The cost of polishing
=40000×9.50
=380000
Hence, this is the answer.
