A rectangular swimming pool measures 25 meters in length, 10 meters in width, and 2 meters in depth. If it is filled with water, calculate the weight of the water in kilograms (density of water = 1000 kg/m³).
["Rectangular Swimming Pool: Volume, Weight of Water, and Important Calculations", "A rectangular swimming pool is a popular choice for residential waterscapes due to its clean lines and efficient use of space. Understanding key measurements—especially volume and water weight—helps with maintenance, budgeting, and planning. In this article, we explore a standard-sized pool and calculate the weight of water it holds when filled.", "### Dimensions and Volume of the Pool", "A typical rectangular swimming pool measures:", "- Length: 25 meters\n- Width: 10 meters\n- Depth: 2 meters", "The volume of a rectangular pool is calculated using the formula:\n[\n\ ext{Volume} = \ ext{Length} \ imes \ ext{Width} \ imes \ ext{Depth}\n]", "Substituting the values:\n[\n\ ext{Volume} = 25, \ ext{m} \ imes 10, \ ext{m} \ imes 2, \ ext{m} = 500, \ ext{m}^3\n]", "This means the pool holds 500 cubic meters of water when full.", "### Calculating the Weight of Water", "Water has a density of approximately 1000 kg/m³. To find the total weight of the water in kilograms, multiply the volume by the density:", "[\n\ ext{Weight} = \ ext{Volume} \ imes \ ext{Density} = 500, \ ext{m}^3 \ imes 1000, \ ext{kg/m}^3\n]", "[\n\ ext{Weight} = 500,000, \ ext{kg}\n]", "So, a 25 m × 10 m × 2 m swimming pool filled to capacity contains 500,000 kilograms of water—equivalent to the weight of about 500 metric tons.", "### Practical Implications", "- Hydrostatic Pressure: The sheer volume means significant pressure on pool walls and floors, requiring strong structural design.\n- Buying Water: If refilling after evaporation or spillage, knowing 1000 liters = 1 m³ helps estimate water needs. For example, filling 500 m³ equals 500,000 liters—enough for hundreds of showers or a large water feature.\n- Weight Distribution: For remodeling or maintenance, knowing the total weight helps assess floor load-bearing requirements.", "### Conclusion", "Understanding the dimensions and water weight of a rectangular pool is essential for homeowners, engineers, and pool designers. With dimensions of 25 meters long, 10 meters wide, and 2 meters deep, this pool holds 500 cubic meters—or 500,000 kilograms—of water. Accurate calculations ensure safe construction, efficient maintenance, and precise planning for water use.", "---", "#### Key Takeaways:", "- Pool volume = 500 m³\n- Water weight = 500,000 kg\n- Ideal for accurate water management and structural design", "Whether you’re building a backyard oasis or managing a commercial facility, precise pool measurements and water weight calculations are vital for optimal performance and safety."]
