Question

Water flows into a tank from a pipe at the rate of 650 cm²/min. The height of the tank is 10 cm. How much of the tank would be filled in 30 minutes?

1. 1,50,000 cm³
2. 1,95,000 cm³
3. 2,00,000 cm³
4. 1,75,000 cm³

Answer 1

Correct Answer - Option 2 : 1,95,000 cm³

Given:

The water flows into a tank from a pipe at the rate of 650 cm²/min.

Height of tank = 10 cm

Concepts used:

Volume of cuboid = length × breadth × height

Calculation:

Flow of water into tank from pipe = 650 cm²/min

⇒ Area of base of tank = 650 cm²

Volume of tank = Area of tank × height

⇒ Volume of tank = 650 cm² × 10 cm = 6,500 cm³

Tank filled in 1 min = 6,500 cm³

⇒ Tank filled in 30 minutes = 6,500 × 30 cm³ = 1,95,000 cm³

∴ Volume of tank filled in 30 minutes is 1,95,000 cm³.
