The volume of a rectangular prism is represented by the function x3 + 11x2 + 20x - 32. The width of the box is x - 1 while the height is x + 8. Find the expression representing the length of the box

The volume of a rectangular prism is computed by a formula volume = length times width times height. So base on your given the volume is represented by x^3+11x^2+20-32 and the width is x-1 and height is x+8 the length is x+4 i hope i answered your question
