Your answer
---------------------

External dimensions of a closed metal box = 66 cm × 36 cm × 21 cm

Thickness of the metal sheet = 0.5 cm

Then,
----------

Internal dimensions of the box : -

Length = [66 - (2 × 0.5)] cm = 65 cm

Breadth = [36 - (2 × 0.5)] cm = 35 cm

Height = [21 - (2 × 0.5)] cm = 20 cm

Capacity of the box = Internal volume

= (65 × 35 × 20) cm³

= 45500 cm³
