Solution

Measurement of a standard brick:
19 cm × 9 cm × 9 cm

The length of the wall = 570 cm
The length of each brick = 19 cm
Number of bricks length-wise
= 570 ÷ 19 = 30

The height of the wall = 45 cm
The height of each brick = 9 cm
Number of bricks height-wise
= 45 ÷ 9 = 5

The breadth of the wall = 18 cm
The breadth of each brick = 9 cm
Number of bricks breadth-wise
= 18 ÷ 9 = 2
