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

36 bricks

Step-by-step explanation:

We are given;

Length of the square path as 18 cm Length of the square brick as 3 cm

We are required to determine the number of bricks that would be laid on the square path.

Number of bricks = Area of the path : area of one brick

Area of a square = l²

Therefore;

Area of the square path = (18 cm) ²

= 324 cm²

Area of square brick = (3 cm) ²

= 9 cm²

Therefore;

Number of bricks = 324 cm² : 9 cm²

= 36 bricks
