    l = 133.02m

    l = 133m (Appropriately)

    Step-by-step explanation:

    The volume of a Square Base Pyramid is expressed as:

    V = Bh

    Where

    B = Base Area (That Square)

    h = Height of the Pyramid.

    To solve for the Base Area, we use the area of a square, which is eqa to (l * l = l^2)

    Having this Understanding, Let's solve on proper now.

    From the Question:

    V = 2,592,276 cubic meters

    h = 146.5 meters.

    Base Area isn't given.

    Therefore:

    V = Bh

    B = V/h

    B = 2,592,276 / 146.5

    B = 17694.72 m^2

    Since we've gotten the value for the Base Area, let's solve for the length of one side of the base.

    Base Area (B) = l^2

    B = l^2

    Recall that B = 17694.72 m^2

    Therefore:

    l^2 = 17694.72 m^2

    l = √ 17694.72 m^2

    l = 133.02 m

    l = 133 m (Approximately)

    The answer to your question is length of a side = 133 m

    Step-by-step explanation:

    Data

    Total volume = 2,592,276 m³

    height = 146.5 m

    length = x

    Process

    1. - Calculate the area of the base

    The Volume of a pyramid = Area of the base x height

    -Solve for area of the base

    Area of the base = Volume of a pyramid/height

    -Substitution

    Area of the base = 2,592,276 / 146.5

    -Result

    Area of the base = 17694.7167 m²

    2. - Calculate the length of one side

    Area of the base = side x side

    Area of the base = side²

    side² = 17694.7167 m²

    side = √17694.7167 m²

    side = 133 m
