Question

how many bricks of size 22cm*10cm*7cm are required to construct a wall 11m long,3.5m gh and 40cm tck ,if the cement and sand used in the construction occupy (1/10)th part of the wall

Answer 1

Answer:

1000 bricks were required to build the wall.

Step-by-step explanation:

Given : Bricks of size 22cm, 10cm, 7cm are required to construct a wall 11m long, 3.5m gh and 40cm tck ,if the cement and sand used in the construction occupy (1/10)th part of the wall.

To find : How many bricks were used?

Solution :

Brick size 22cm, 10cm, 7cm

Volume of the brick is $V_B=22\times 10\times 7$

Wall size 11 m long,  3.5m gh and 40cm tck

Convert into same unit,

1 m=100 cm

Length 11 m = 1100 cm

Height 3.5 m=350 cm

Width = 40 cm

Volume of the wall is $V_W=1100\times 350\times 40$

According to question,

$\text{Number of bricks}= \frac{1}{10}\times \frac{\text{Volume of the wall}}{\text{Volume of the brick}}$

$\text{Number of bricks}= \frac{1}{10}\times \frac{1100\times 350\times 40}{22\times 10\times 7}$

$\text{Number of bricks}=1000$

Therefore, 1000 bricks were required to build the wall.
