Breadth of tank if length = 2.5m, depth = 10m, volume = 50,000L:

This problem requires knowledge of the volume formula for a rectangular prism (tank) and unit conversion between liters and cubic meters.

• Correct Answer: 2 m. First, convert the volume from liters to cubic meters: 50,000 L = 50 m³ (since 1 m³ = 1000 L). The formula for the volume of a rectangular tank is Volume = Length × Breadth × Depth. Substituting the given values, we have 50 m³ = 2.5 m × Breadth × 10 m. This simplifies to 50 = 25 × Breadth. Therefore, Breadth = 50 / 25 = 2 m.
• Distractors: Options A (1 m), C (2.5 m), and D (5 m) are results of incorrect calculations or unit conversions.
