Advertisements
Solution
Let the length of each brick be 10 cm.
Length of wall = 1 m
As the length of brick in cm, the length of the wall will be converted to cm for calculation.
We know that 1 m = 100 cm
Length of wall (in cm) = 1 × 100 cm = 100 cm
Number of bricks required to make a 100 cm long wall
= Length of wall ÷ Length of 1 brick
= 100 ÷ 10
= 10
The number of bricks required to make 1 m long wall = 10.
