Algebra II - Unit 2 Polynomials

Mai wants to make an open-top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard is 10 centimeters by 10 centimeters. The volume V(x) in cubic centimeters of the open-top box is a function of the side length x in centimeters of the square cutouts. a. Write an expression for V(x).

• V(x) = x (10 - 2x) (10 - 2x)

• V(x) = x (10 + x) (10 + x)

• V(x) = (10 - 2x) (10 -2 x)

• V(x) = x (10 - x) (10 - x)
