Answer: 32 inches
Step-by-step explanation:
Assuming that the base of the box is a rectangular, we can use the following formula for the area of rectangular:
The given information is
Area: 112 [tex]in^{2}[/tex]
Height: 3.5 in
Substituting the given information in the formula,
3.5in * Width = 112 [tex]in^{2}[/tex]
dividing 3.5 inches in both sides,
Width = 112 [tex]in^{2}[/tex] / 3.5 in = 32 in
The width of the base of the box is 32 inches
