Anish hired two workers to construct a 1.5 m long, 0.4 m high, and 0.25 m thick wall. They use bricks measuring 9 cm × 5 cm × 3 cm which costs Rs. 9 per brick. The sand and cement occupy 10% of the total volume of the wall which costs Rs. 1000. Determine the total construction cost of the wall for Anish if he is paying 20% of the cost of the wall to the workers.
