To find the cost of polishing a 60m by 40m warehouse floor at Rs. 80 per sq.cm, calculate the area in square meters, convert it to square centimeters, and multiply by the cost per square centimeter, resulting in a total cost of Rs. 1,920,000,000.
To calculate the cost of polishing the floor of a warehouse that is 60m long and 40m wide, we first need to find the area of the floor. The formula for the area of a rectangle is length × width. Using the dimensions provided, the area is 60m × 40m = 2400m². Since the cost is given per square centimeter, we must convert square meters to square centimeters. There are 10,000 square centimeters in a square meter, so the total area in square centimeters is 2400m² × 10,000cm²/m² = 24,000,000cm². Finally, multiply the area by the cost per square centimeter to find the total cost: 24,000,000cm² × Rs. 80/cm² = Rs. 1,920,000,000.
Therefore, the cost of polishing the warehouse floor is Rs. 1,920,000,000.
