Question

find the number of square tiles of side 8 cm required to cover a wall 10 metre by 6 metre​

Answer 1

Answer:

Length of the wall = 10m

Breadth of the wall = 6m

Area = L × B = 60m^2

Now,

Side of squared tile = 8 cm or, 8/100 m = 0.008 m

so, area of tile = 0.0064 m^2

Now,

no. of tiles = area of wall / area of tile

So, no. of tiles = 60/0.0064

or, 60/64/10000 = (60 × 10000)/64

No. of tiles = 9375 tiles

Hope you understood :)
