Answer:
use the pythagoras theorem
Step-by-step explanation:

we know that
the volume of a rectangular prism is equal to

where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have




<u>Find the length of the box</u>
Using a graph tool-------> we will determine the roots of the equation of volume
see the attached figure
the roots are

so

therefore
<u>the answer is</u>
the length of the box is equal to 
Yea but it would be an obtuse triangle
FOIL this out. 3x*x = 3x^2; 3x*8= 24x; -8*x = -8x; -8*8=-64. Combine like terms to get
