maria [59]

Answer:

Rs. 4,200,000

Step-by-step explanation:

Given :

Volume of brick = 500cm³

Dimension of wall : 200m×0.5m×1.5m

Converting to cm

Volume of compound wall:

(200 * 100) * (0.5 * 100) * (1.5 * 100)

20000cm * 50cm * 150cm=

= 150000000cm³

Volume of compound wall / volume of brick

1500000000 cm³ / 500 cm³

= 300000

Price per brick = Rs. 14

Total price = 14 * 300000 = Rs. 4,200,000
