**Answer:**

100 bricks are required to construct the wall.

**Step-by-step explanation:**

**All calculations should be done with unit in centimetres.**

volume of the wall = length * width * height

= 15 * 20 * 200

= 60000 cm³

one brick volume = length * width * height

= 15 * 8 * 5

= 600 cm³

So to fill the entire wall with x walls: volume of wall / one brick volume

→ 60000 / 600

→ 100 bricks
