Answers
Step-by-step explanation:
Given
A bathroom is in the form of cuboid of dimensions 3 metre , 3 metre , 6 metre how many square tiles are required to fix all the faces if the side of the tile is 5 cm.
We know that surface area of a cuboid has 2 square and 4 rectangles.
So surface area will be 2 x l^2 + 4 (l x b)
= 2 x 3^2 + 4 (6 x 3)
= 2 x 9 + 4 x 18
= 18 + 72
= 90 sq m
Now given side of a tile is 5 cm = 0.05 m
So area of square tile = l^2
= (0.05)^2
= 0.0025 sq m.
Now number of tiles = surface area of cuboid / area of one tile
= 90 / 0.0025
= 36,000 tiles.
Therefore number of tiles required to fix will be 36,000.
