<b> Solution

Given :-

measure brick

length = 5cm

breadth = 25cn

height = 10 cm

volume of brick = (length *breadth*height)

volume of brick = ( 5*25*10)

volume of brick = 1250cm³

Then we find require contract of brick

length = 20 m

1m = 100 cm

20 * 100 = 2000cm

breadth = 80cm

height = 6m

1m. = 100 cm

6*100 = 600 cm

we use volume = L* B*H

volume = 2000* 80* 600

Volume = 96000,000 cm³

No bricks required = 96000,000/ 1250

Bricks required = 76,800

Answer = 76,800
