Question

A bathroom is in the form of a cuboid of dimension 3m*3m*6m. How many square tiles are required to fix to all the faces if side of a tiles is 5cm

Answer 1

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.
