How many bricks, each measuring 25 cm × 11,25 cm × 6 cm, will be needed to build a wall of 8 m × 6 m × 22,5 cm
To find out how many bricks are needed, we need to calculate the volume of the wall and divide it by the volume of one brick.
Volume of the wall = length × width × height
= 8m × 6m × 22.5cm
We need to convert the measurements to the same units. 1 meter = 100cm, so the wall's dimensions become:
= 800cm × 600cm × 22.5cm
Volume of one brick = length × width × height
= 25cm × 11.25cm × 6cm
Now we can calculate the number of bricks needed:
Number of bricks = Volume of the wall / Volume of one brick
= (800cm × 600cm × 22.5cm) / (25cm × 11.25cm × 6cm)
Canceling out the units:
= (32 × 24 × 2) / (1 × 4 × 1)
= 1536 / 4
= 384
Therefore, 384 bricks will be needed to build the wall.
To calculate the number of bricks needed, first convert the dimensions of the wall into centimeters:
8 m = 800 cm
6 m = 600 cm
22.5 cm = 22.5 cm
Next, calculate the volume of each brick:
Volume = length × width × height
Volume = 25 cm × 11.25 cm × 6 cm
Volume = 1687.5 cm³
Then, calculate the volume of the wall:
Volume = length × width × height
Volume = 800 cm × 600 cm × 22.5 cm
Volume = 10,800,000 cm³
Finally, divide the volume of the wall by the volume of each brick to calculate the number of bricks needed:
Number of bricks = Volume of wall / Volume of each brick
Number of bricks = 10,800,000 cm³ / 1687.5 cm³
Number of bricks = 6400
Therefore, you will need 6400 bricks to build the given wall.
To calculate the number of bricks needed to build the wall, we need to find the total volume of the wall and divide it by the volume of each brick.
Step 1: Convert the dimensions of the wall into the same unit of measurement:
- 8 m = 800 cm
- 6 m = 600 cm
- 22.5 cm (already in the correct unit)
Step 2: Calculate the volume of the wall:
Volume = Length × Width × Height
Volume = 800 cm × 600 cm × 22.5 cm
Volume = 10,800,000 cm³
Step 3: Convert the dimensions of each brick into the same unit of measurement:
- 25 cm
- 11.25 cm
- 6 cm
Step 4: Calculate the volume of each brick:
Volume = Length × Width × Height
Volume = 25 cm × 11.25 cm × 6 cm
Volume = 1687.5 cm³
Step 5: Divide the total volume of the wall by the volume of each brick to find the number of bricks needed:
Number of bricks = Total volume of the wall / Volume of each brick
Number of bricks = 10,800,000 cm³ / 1687.5 cm³
Number of bricks = 6412.97
Since we can't have a fractional number of bricks, we round up to the nearest whole number.
So, you will need approximately 6413 bricks to build the wall.
