Answer:
80 bricks
Step-by-step explanation:
Area of brick = 20 cm x 14 cm = 280 cm²
Area of floor = 16m x 14 cm = 1600 cm x 14 cm = 22400 cm²
If the bricks were to completely cover the floor, we will have:
No. of bricks * Area of brick = Area of floor
=> No. of bricks * 280 = 22400
=> No. of bricks = 22400/280
= 80
Please note that the floor has width of 14 cm and the brick also has width of 14 cm. This means that one side of a brick can fully cover one side of the floor. Due to this, we will only need full bricks.
