Answer: Width of box must be 6 inches.
Step-by-step explanation:
Since we have given that
Length of box = 17 inches
Height of box = 1 inch
Width of box be 'b'.
Volume of box = 102 cubic inch.
As we know that
[tex]Volume=Lbh\\\\102=17\times 1\times w\\\\102=17w\\\\w=\dfrac{102}{17}\\\\w=6[/tex]
Hence, width of box must be 6 inches.
