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. Â
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". Â
The sides are now missing a length of x from each end. Â
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.
