Question

Given that the length of each brick is 10 cm. Affi wants to make a wall 1 metre long. How many bricks will she need to put in a line?

Answer 1

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 $=\frac{Lengthofwall}{Lengthof1brick}=\frac{100}{10}=10$
The number of bricks required to make a 1 m long wall = 10.
