    Let V be total volume of wooden block and V’ is the volume that lies immersed in the liquid.
    Using principle of floatation,
    Weight of wooden block = weight of the liquid displaced by the immersed portion of the wooden block

    So, the volume fraction of wooden block below the liquid surface = 1 – 0.4815 = 0.5185

    Understanding the Problem
    The problem involves a wooden block and a metallic piece floating in a liquid. We need to determine the volume fraction of the metallic piece that lies above the liquid surface.
    Given Data
    - Relative density of the wooden block = 0.65
    - Relative density of the liquid = 1.35
    Key Concepts
    - Relative Density: The ratio of the density of a substance to the density of a reference substance (usually water).
    - Buoyancy Principle: An object floats if its density is less than that of the liquid. The submerged part of the object displaces a volume of liquid equal to its weight.
    Calculating Densities
    - Density of wooden block = 0.65 * 1000 kg/m³ = 650 kg/m³
    - Density of liquid = 1.35 * 1000 kg/m³ = 1350 kg/m³
    Determining the Fraction Submerged
    To find the volume fraction of the wooden block submerged in the liquid, use the concept of buoyancy:
    - Volume submerged = Weight of the block / Density of the liquid
    - Weight of the block = Volume of the block * Density of the block
    Assuming the volume of the wooden block is V:
    - Volume submerged = (V * 650) / 1350
    - Ratio of submerged volume to total volume = 650 / 1350 = 0.481
    Volume Above the Surface
    The volume fraction of the wooden block above the liquid surface is:
    - Volume above = 1 - Volume submerged = 1 - 0.481 = 0.519
    Conclusion
    Thus, the volume fraction of the metallic piece that lies above the liquid surface is 0.519. This means that approximately 51.9% of the block's volume is above the liquid surface, confirming the given answer.
