Answer:
The length of each side of the box = 9 inches.
Step-by-step explanation:
Here, the volume of the given packing box = 729 cubic inches
Let us assume the length of 1 side of box = s inches
Also, VOLUME OF CUBE = [tex](side)^3[/tex]
[tex]\implies 729 =(s)^3\\\implies s = \sqrt[3]{729} = \sqrt[3]{(9)^3} = 9\\\implies s = 9[/tex]
Hence the length of each side of the box = 9 inches.
