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
