Answer:

So, you would need 16,000 bricks of dimensions 20 cm × 10 cm × 5 cm to build the wall.

Explanation:

To find the number of bricks required to build the wall, we need to calculate the total volume of the wall and then divide it by the volume of a single brick.

The dimensions of the wall are:

Length = 16 m

Height = 2 m

Depth = 0.5 m

The volume of the wall is calculated as follows:

Volume = Length × Height × Depth

Volume = 16 m × 2 m × 0.5 m

Volume = 16 m³

Now, let's consider the dimensions of a single brick:

Length of brick = 20 cm = 0.2 m

Width of brick = 10 cm = 0.1 m

Height of brick = 5 cm = 0.05 m

The volume of a single brick is calculated as follows:

Volume of a brick = Length × Width × Height

Volume of a brick = 0.2 m × 0.1 m × 0.05 m

Volume of a brick = 0.001 m³

Now, to find the number of bricks required, we divide the volume of the wall by the volume of a single brick:

Number of bricks = Volume of the wall / Volume of a brick

Number of bricks = 16 m³ / 0.001 m³

Number of bricks = 16,000
