Question

how many bricks each 25 cm long 10 cm wide and 7.5 CM thick will be required for a wall 15 M long 2.5 metre high and 1.25 M thick​

Answer 1

$\pink{Measurements \: Of \: Brick}$

Length of brick = 25 cm ,0.25m

Breadth of brick = 10cm , 0.1m

thickness of brick =7.5cm , 0.075m

$\pink{Measurements \: Of \: wall}$

Length of wall = 15m

Breadth of wall = 2.5m

thickness of wall = 1.25m

$\huge\blue{number \: of \: bricks}$

$= \frac{volume \: of \: wall \: }{volume \: of \: one \: brick}$

$= \frac{15 \times 2.5 \times 1.25}{0.25 \times 0.1 \times 0.075}$

$= \frac{15 \times 25 \times 125 \times 100 \times 10 \times 1000}{25 \times 10 \times 75 \times 10 \times 100}$

$= 1000 \times 25$

$= 25000$

25000 bricks will be required for the wall
