Answer:
s = 6 feet
Step-by-step explanation:
Given that,
The volume of the cube, V = 216 feet³
We need to find the side length for the cubical box. We know that the volume of the cube is given by :
, s is the side length of the box.
So,

So, the side length for the cubical box is equal to 6 feet.
Try this solution, note, the suggested option is not the shortest way.
P² + 14p + 40
= p² + 10p + 4p + 40
= p(p+10) + 4(p+10)
= (p+10)(p+4)
