A rectangular water tank measures 100 cm length, 50 cm width, and 30 cm height. If the tank is filled to 50% of its capacity, how much water (in liters) is in the tank?
Show answer & explanation
Correct answer: B
Explanation
Length = 100 cm, Width = 50 cm, Height = 30 cm, Filled = 50%
According to the formula:
Volume = l × b × h
Volume = 100 × 50 × 30 = 150,000 cm³
50% = 150,000 / 2 = 75,000 cm³
1 Liter = 1,000 cm³
Water = 75,000 / 1,000 = 75 Liters
