clare wants to make an open-top box by cutting out corners of a 30 inch by 25 inch piece of poster board and then folding up the
sides. The volume V(x) in cubic inches of the open-top is a function of the side lengh x in inches of the square cutouts. Write an expression for V(x).
area equals 36 and 3 fourths because if you cut the triangle off of one of the sides and add it to the other side it makes a rectangle then you do length times width to find regular area of a rectangle.
