Answer:
36,000
Step-by-step explanation:
Assuming there are no Door or Windows given in the Question.
To find number of tiles =
(Total Surface Area of Cuboidal Bathroom) ÷ (Area of one tile)
Total Surface area of Cuboidal Bathroom = Total Surface Area of Cuboid
= 2(LB + BH + HL)
=2(3x3 + 3x6 + 6x3)
=2(9 + 18 + 18)
= 90 m² or 900000 cm² [∵ 1 m² = 10000 cm²]
Now, Area of one tile = side x side
= 25 cm²
Number of tiles required =
(Total Surface Area of Cuboidal Bathroom) ÷ (Area of one tile)
= 900000 ÷ 25
= 36,000
Hence, 36, 000 tiles required to fix all the faces of the cuboidal bathroom.
