To find the Number of Bricks or Tiles when Area of Path and Brick is given

To find the number of bricks or tiles when area of path and brick is given are discussed here. We need to divide area of path or wall by area of a brick or tile.

Number of bricks or tiles = area of path or wall ÷ area of a brick or tile.

For Example:

1. Find the number of bricks to be laid in a square path of side 18 cm, if the side of each brick is 3 cm.

Solution:

Area of path = 18 × 18 sq. cm.

Area of each brick = 3 × 3 sq. cm.

Therefore, number of bricks = area of path ÷ area of each brick.

= (18 × 18) ÷ (3 × 3)

= 324 ÷ 9

= 36

Therefore, number of bricks = 36.

2. Find the number of bricks to be laid in a square path of side 25 cm, if the side of each brick is 5 cm.

Solution:

Area of path = 25 × 25 sq. cm.

Area of each brick = 5 × 5 sq. cm.

Therefore, number of bricks = area of path ÷ area of each brick.
