1.
The
following
shipment
needs
to
be
transported
in
an
ocean
container.
The
shipment
will
be
loose-
loaded
(un-palletized).
Details:
220
cartons
of
clothing.
Dimensions
of
each
carton
are
18

of
each
carton
is

be
more
than
enough

The
following
shipment
needs
to
be
transported
in
an
ocean
container.
Details:
10

(179

the
total

b)
What
is
the
total
weight
of
the
shipment?
1,800
kg
x
10
Jeeps
=
18,000
kg
c)
How
many
and
what
type(s)
of
ocean
containers
do
you
estimate
are
required
to
move
this
shipment
most
economically?
Because
of
the
width
of
the
Jeeps,
we
need
to
consider
only
the
length
of
the
vehicle.
On
this
basis,
a
20-ft
standard
container
can
only
hold
1
Jeep,
whereas
a
40-ft
standard
container
can
hold
2
Jeeps.
20-ft
standard
container
is
232inlL
=
165in
=
1.5
=
1
40-ft
standard
container
is

inL
=

=
5
x
40-ft
standard
containers
are
required.
24.208
m?3
in
each
container
(within
55-60
m3
average).
3,600
kg
per
container
(within
25,000
kg
maximum
payload
capacity).
5
x
40-ft
standard
containers
would
be
cheaper
that
10
x
20-ft
standard
containers,
and
less
space
is
wasted.
