Therefore total cost to build the wall is = 1,139,000
Step-by-step explanation:
Given that , the rectangular compound wall of a house measure 20 m long, 15 m broad , 5 m high and 12 cm=0.12 m thick.
The surface area of the wall is
=2(length×height+broad×height)
=2×height (length+broad)
The volume of the wall
=2×height (length+broad)×thickness
= 2×5(20+15)×0.12 m³
=42 m³
=42×10⁶ cm³
The dimension of brick is 15 cm×10 cm× 5 cm.
The volume of one brick =(15×10×5) cm³
=750 cm³
The number of brick required to make the wall
=56000
Given that the rate of cost of brick is Rs. 20,000 per thousand brick.
Therefore the cost of one brick is = Rs. 20.
The cost of 56000 brick is = Rs.(56000×20) =Rs.1,120,000
5 days is required for labour to finish the work charges Rs. 950 per labour per day.
Total lobour charge =Rs. (5×4×950)
=Rs. 19,000
Therefore total cost to build the wall is
= cost price of 56,000 brick + lobour charge
=Rs.(1,120,000+19,000)
=Rs.1,139,000
