  1. Answer:

    The volume (density) of cement that will be needed to cover this hollow pipe is:

    = 50,000 kg/m³

    Step-by-step explanation:

    Length of a cylindrical pipe = 5m

    Width of the cylindrical pipe = 4m

    Depth of the cylindrical pipe = 2.5m

    The cubic meters of the cylindrical pipe = 5 * 4 * 2.5 = 50m³

    1 cubic meter is equal to 1,000 kilogram

    Therefore, the volume (density) of cement that will be needed to cover this hollow pipe is:

    = 50 * 1,000

    = 50,000 kg/m³
