can u please answer it step by step........the outer measure of the rectangular compound wall of a house are 20 m long, 15m broad, 5m high and 12 cm thick. Find the cost of the building the walls by using bricks of size 15cm × 10cm× 5cm where the rate of the cost of bricks is Rs. 2000 per 1000 bricks. 5 days is required for 4 labours to finish the work and the labour charge is Rs. 950 per day per labour...

Answer:
Here we will get;
- Volume of compound wall as 36,00,000 m³
- Volume of brick as 7.5m³
- Number of bricks needed as 64,000
- Cost of bricks as 1,28,000
- Cost for labours as 19,000
- Total cost needed to build the compound is 1,47,000
Step-by-step explanation:
- First, we should find the volume of the compound wall of the house.
- Then we should find the volume of one brick.
- Now we should divide the volume of the compound wall with the volume of the brick.
- And find the cost of bricks Rs,2000 per 1000 bricks.
- And Calculate the labor's charge.
Volume of the compound wall = 2000 * 1500 * 12
=3,60,00,000 cm
= 36,00,000 m³
Volume of 1 brick = 15 * 10 * 5
= 750 cm
= 7.5m³
Now dividing volume of compound wall with volume of brick = 36,00,000/7.5
= 3,60,00,000/75
=4,80,000cm³
∴48,00,000/75 = 64,000
Cost of the bricks is = 2000/1000
= 2
∴64,000*2= Rs. 1,28,000
For 1 labour cost is= 950
For 4 labours cost is = 950*4= 3,800
For 5 days cost is = 3800*5= 19,000
Therefore total cost to do is = 1,28,000+19,000=1,47,000
