  • The volume of a pyramide is

    V = Ab.h/3

    In this case Ab = 7 . 7 = 49

    V = 49.h/3

    V = 49.11/3

    V = 539/3

    Now let's see the cone volume

    V = π.r².h/3

    V = π.3².11/3

    V = π.3.11

    V = 33π

    Now we just remove the cone from the pyramid

    539/3 - 33π = 75,994cm³

    Rounding its 76cm³
