Assuminhg the ark has a shoe-box (cuboid) shape it´s volume would be:

We have this three measurements (
) and it can be as simple as replacing them in the equation and solving but they are in all in
. We will convert them to
because the problem requires the answer in
. In order to do this we will use the given equivalences:

and another one:

First we will convert from cubits to palms:

now from
to
:

now from
to
:

We can calculate the Volume now like this:

The volume of trhe ark would be 
Okay add 78 and 66. Then add 96 and 108. It should be 144 by 204. I know math is hard, but when you work at it you can do amazing things! I hope that helps you.
see the attached figure to better understand the problem
we know that
The volume of the cone is equal to

in this problem

Substitute the values in the formula above

therefore
the answer is
The volume of the nose cone is
