The dimensions of a rectangular parallelepiped tank are 4 m × 3 m × 2.5 m. If it is filled with water and the cost of water is ₹25 per 1000 liters, what is the total cost to fill the tank? (1 m³ = 1000 liters)
Show answer & explanation
Correct answer: C
Explanation
Length = 4 meters
Width = 3 meters
Height = 2.5 meters
Volume = 4 × 3 × 2.5 = 30 m³
1 m³ = 1000 liters
30 m³ = 30,000 liters
Cost of water = ₹25 per 1000 liters
Total cost = (30,000 ÷ 1000) × 25 = 30 × 25 = ₹750
