Expert Answer

Length of the metallic sheet = 48 cm

Breadth of the metallic sheet = 56 cm.

When a square of 8 cm is out off from each corner to form an open box, then

Length of the open box,

 l = 48 cm – 8 cm – 8 cm = 32 cm

Breadth of the open box,

 b = 56 cm – 8 cm – 8 cm = 40 cm

Height of the open box, 

h = side of the out off square = 8 cm

Volume of the open box = l × b × h 

V = 32 cm × 40 cm × 8 cm = 10240 cm3
