Answer:
The second option :: V = [tex](25-2x)(20-2x)x[/tex] is correct.
Step-by-step explanation:
The vertical side was 25 inches before cutting out the corners.
The horizontal side was 20 inches before cutting out the corners.
So now, if you fold all of the corner up, you get a box that has a height of "x".
The sides are now missing a length of x from each end.
So the longer edges of the box are now [tex](25-2x)[/tex] inches
The shorter edges of the box are now [tex](20-2x)[/tex] inches
The volume of a box is given by V = length x width x height
So, here the volume becomes:
V = [tex](25-2x)(20-2x)x[/tex] cubic inches.
