Answer:

Step-by-step explanation:
The volume
of a solid is given by the multiplication of its three dimensions:

In this case we have two similar solids with volumes
and
, and we only have information about the height of each solid
and
.
Now, there is a theorem for similar solids, which establishes the ratio of their volume is
and the ratio of one of their corresponding sides (the height in this case) is
.
Knowing this, we can write the following relation:

Substituting the known values:

Fially finding
:
