    Answer:

      5

    Step-by-step explanation:

    The volume of a right square pyramid is given by the formula …

      V = 1/3Bh

    where B is the area of the base.

    The volume of the larger pyramid will be …

      V’ = 1/3(5B)h

    So, the ratio of volumes is …

      V’/V = (1/3(5B)h)/(1/3Bh)

      V’/V = 5

    The ratio of volumes is 5.
