A cubic container, with sides of length, x inches, has a volume equal to x^3 cubic inches. The height of the container was decreased and the length was increased so that the volume is now modeled by the expression

x^3+4x^2-5x

By how many feet were the height and length changed?

(Hint: Volume = length times width times height)

x(x+5)(x-1)

so I would say the length was increased by 5, the width remained the same and the height was shortened by 1
