Question

the length of a wall is 35 M and breadth is 82 M and height is 25 m if the volume of a brick is 25 CM * 1 cm *7 cm. Find out the number of bricks required to make the wall?​

Answer 1

$\Huge{\textbf{Solution;}}$

$\huge{\textsf{Step 1 }}$:-. Find the volume of wall

Given:-

Length of wall = 35 m

Breadth of wall = 82 m

height of wall = 25 m

Volume of a cuboid = l*b*h

Now,

Volume of the wall = $35\times 82\times 25$

Volume of the wall = 71, 750

$\huge{\textsf{Step 2:}}$

Find the volume of one brick

Volume of brick = 25 /100*7/100*1/100
= 0.000175




$\huge{\textbf{Step 3 :}}$

Find the no of bricks

No of bricks = 71,750/0.000175



=410,000,000
