• A. 84
• B. 96
• C. 88
• D. 108

Answer 1

The correct option is B 96

The amount of cardboard required to make the cubical box is the area of the given net.


Hence,
Area of net = Area of 6 square faces
Area of each square = side x side
$=4\times 4$
$=16\text{sq ft}$
Total area = 6 x area of each square
$=6\times 16$
$=96\text{sq ft}$
