Answer:
6 in.
Step-by-step explanation:
Rectangular prism
V = lwh       l = 8   W = 3    h = 9
   = 8(3)(9)
   = 216
Cube
 
   where s = length of side
216 = 
  = 6
 
        
             
        
        
        
Length = 20 ft
If he uses 60 ft of fencing to line his rectangular backyard, then the perimeter is 60 ft.
Perimeter formula is ((Width × 2) + (Length × 2))
 
10 × 2 = 20
20 × 2 = 40
40 + 20 = 60
