Question

how many bricks each of size 25 cm into 13.5 cm into 6 CM will be required to build a wall 8 metre long 5.4 M high and 33 CM thick​

Answer 1

To solve these types of questions, simply divide the volume of the wall with the volume of one brick to get the required number of bricks to be used to build the wall.

Length of wall = 8 m = 800 cm
Height of wall = 5.4 m = 540 cm
Thickness or width of wall = 33 cm
Volume of the wall = L*B*H
= 800*540*33
= 14256000 cu cm

Volume of one brick = 25*13.5*6
= 2025 cu cm

Total number of bricks required = Volume of the wall/Volume of one brick
= 14256000/2025
= 7040 

So, 7040 bricks will be needed.
Answer.

Answer 2

Answer:

Answer is 7040 bricks required to build wall

Step-by-step explanation:

$number \: of \: bricks = \frac{volume \: of \: wall}{volume \: of \: bicks} \\ = \frac{800 \times 33 \times 540}{25 \times 13.5 \times 6} \\ = 7040$
