Solution

Length of brick = 10 cm
Length of wall = 1 m
As the length of brick in cm, the length of the wall will be converted to cm, 1 m = 100 cm
Thus, the length of wall = 100 cm.
Number of bricks required to make a 100 cm long wall $= \frac{L e n g t h o f w a l l}{L e n g t h o f 1 b r i c k} = \frac{100}{10} = 10$
The number of bricks required to make a 1 m long wall = 10.
