Answer:

2952 square centimeters are needed to cover the exterior of the box.

Explanation:

We need to cover five external faces of the box. The surface area formula (
A_(s)), measured in square centimeters, is derived from surface area formula for parallelpiped:


A_(s) = w\cdot l + 2\cdot w\cdot h + 2\cdot l \cdot h (1)

Where:


w - Width, measured in centimeters.


l - Length, measured in centimeters.


h - Height, measured in centimeters.

If we know that
w = 36\,cm,
l = 23\,cm and
h = 18\,cm, then the outer surface area of the storage is:


A_(s) = (36\,cm)\cdot (23\,cm)+2\cdot (36\,cm)\cdot (18\,cm)+2\cdot (23\,cm)\cdot (18\,cm)


A_(s) = 2952\,cm^(2)

2952 square centimeters are needed to cover the exterior of the box.
