Detailed Solution
Download Solution PDFGiven:
Side of cubical tank = 50 cm
Volume of water taken out = 61 litres = 61000 cm3
Formula used:
Volume of water removed = Area of base × Drop in water level
Area of base = Side × Side
Calculation:
Area of base = 50 × 50 = 2500 cm2
Volume of water removed = Area of base × Drop in water level
⇒ 61000 = 2500 × Drop in water level
⇒ Drop in water level = 61000 ÷ 2500
⇒ Drop in water level = 24.4 cm
∴ The correct answer is option (1).
