Answer:

12500

Step-by-step explanation:

length, breadth and height of wall are 20 m , 0.25 m and 2.5 m respectively

Then volume of wall = 20×0.25×2.5 = 12.5 m³ = 12.5×1000000 =12500000 cm³

length, breadth and height of 1 brick are 20 cm , 10 cm and 5 cm respectively

then volume of 1 brick = 20×10×5 = 1000 cm³

No. of bricks = (12500000÷1000)= 12500
