Answer 2

Answer:

The bricks used existed in 17500.

Step-by-step explanation:

Given:

a wall of dimensions 50 cm x 40 cm x 300 cm with the bricks each of size 2 cm x 3 cm x 5 cm

To find:

the number of bricks used to construct the wall is?

Step 1

The entire volume of the wall is

= 50 $\times 40 \times$ 300

= 6,00,000

If the motors cover a space of $\frac{1}{8}$ then the bricks cover a volume of $\frac{7}{8}$.

$\frac{7}{8}$ of 6,00,000 = 525000.

Step 2

To find the volume of brick.

= 2 $\times$ 3 $\times$ s

= 30 cm

Divide the total volume by the volume of bricks.

Step 3

To find the bricks

= 525000/30

= 17500

Therefore, the bricks used existed in 17500.
