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

Answer 1

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.
