How many bricks, each measuring 25cm x 11,25 cm x 6 cm, will be needed to build a wall of 8 m height x 22,5 cm

To calculate the number of bricks needed, we first need to convert the dimensions of the wall to the same unit as the bricks (cm).

8 m = 800 cm
22.5 cm = 22.5 cm

Now, let's calculate the volume of each brick:

25 cm x 11.25 cm x 6 cm = 1687.5 cm³

Next, let's calculate the total volume of the wall:

800 cm x 22.5 cm x 6 cm = 108,000 cm³

Now, let's determine the number of bricks needed by dividing the total volume of the wall by the volume of each brick:

108,000 cm³ / 1687.5 cm³ = 64 bricks

Therefore, 64 bricks will be needed to build the wall.

To determine the number of bricks needed, we can break down the problem into smaller steps:

Step 1: Calculate the volume of one brick
The volume of one brick can be calculated by multiplying its length, width, and height:

Volume of one brick = Length x Width x Height
= 25 cm x 11.25 cm x 6 cm
= 1687.5 cm³

Step 2: Convert the measurements of the wall to the same unit
The height of the wall is given as 8 m, but the measurements of the bricks are in centimeters. We need to convert the height of the wall to centimeters:

Height of the wall = 8 m x 100 cm/m
= 800 cm

Step 3: Calculate the total volume of the wall
To find the total volume of the wall, we need to multiply the height of the wall by the width:

Total volume of the wall = Height of the wall x Width
= 800 cm x 22.5 cm
= 18,000 cm²

Step 4: Determine the number of bricks needed
To calculate the number of bricks needed, divide the total volume of the wall by the volume of one brick:

Number of bricks needed = Total volume of the wall / Volume of one brick
= 18,000 cm² / 1687.5 cm³
≈ 10.66

Since we cannot have a fraction of a brick, we would need to round up to the nearest whole number. Therefore, we would need approximately 11 bricks to build the wall.

To determine the number of bricks needed to build the wall, we need to calculate the area of the wall and the area of one brick. Then we can divide the total area of the wall by the area of one brick to find the number of bricks required.

1. Calculate the area of one brick:
The area of one brick is equal to the product of its length, width, and height. In this case, the dimensions of the brick are given as 25 cm x 11.25 cm x 6 cm. Therefore, the area of one brick is:
25 cm * 11.25 cm * 6 cm = 1687.5 sq cm.

2. Convert the height of the wall to centimeters:
The height of the wall is given as 8 m. Since 1 m is equal to 100 cm, the height of the wall in centimeters is:
8 m * 100 cm/m = 800 cm.

3. Calculate the area of the wall:
The area of the wall is equal to the product of its height and length. The length is given as 22.5 cm. Therefore, the area of the wall is:
22.5 cm * 800 cm = 18,000 sq cm.

4. Calculate the number of bricks needed:
To find the number of bricks required, we need to divide the total area of the wall by the area of one brick:
Number of bricks = Area of the wall / Area of one brick
Number of bricks = 18,000 sq cm / 1687.5 sq cm

Dividing these two numbers, the total number of bricks needed to build the wall is approximately 10.67.

However, since we cannot have a fraction of a brick, we need to round up to the nearest whole number. Therefore, you would need a minimum of 11 bricks to build the wall.
