Step-by-step explanation:
Length of the metallic sheet = 48 cm
Breadth of the metallic sheet = 36 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 = 36 cm – 8 cm – 8 cm = 20 cm
Height of the open box, h = side of the out off square = 8 cm
Volume of the open box = l × b × h = 32 cm × 20 cm × 8 cm = 5120 cm3
Thus, the volume of the open box is 5120 cm3.
