1. The problem statement, all variables and given/known data A package sent by a courier has the shape of a square prism. The sum of the length of the prism and the perimeter of its base is 100cm. Write a polynomial function to represent the volume V of the package in terms of x. width and height are in x centimeters, length is in y centimeters 3. The attempt at a solution 4x+y=100 4x+y-100 V(x)=(x^2)(y)(4x+y-100) V(x)=(4x^3y + x^2y^2 - 100x^2y) V(x)=x^2y(4x+y-100) This is as far as I got, am I going in the right direction? Where did I go wrong?
