Answer:
Option B is the correct answer
Step-by-step explanation:
After removing squares with side 4 inch long, the open box will have following dimensions:
Length = x + 9 - 4 - 4 = (x + 1) in
Width = x - 4 - 4 = (x - 8) in
Height = side of square = 4 in
It is given that volume of the open box is 64 cubic inches.
[tex] \therefore \: l \times w \times h = 64 \: {in}^{3} \\ \\ \purple{ \bold{ (x + 1)(x - 8)(4) = 64 \: {in}^{3} }}[/tex]
