    First, substitute 5 for x in the 2 equations: \(\ \Huge (5)+6; 9(5)+6).\)

    wouldn't it be easier to multiply with x; create the polynomial, then substitute?

    Perhaps, but there is less room for error using this method. I'll show you how find the polynomial, as well. Now, the Volume is Height x Width x Length: So the volume is: \[\ 8\times11\times51= Volume\]

    Now, The Easiest Way to Multiply is to Use a Table, to Foil the two polynomials: |dw:1338768144332:dw|

    So, That gives us \(\ \Huge 9x^2+60x+36 \). There's also an \(\ \Huge 8 \), so \(\ \Huge 8(9x^2+60x+36) \). You can factor a three out of the parenthesis, because 3 is a factor of all three terms. That gives you for a final answer: \(\ \Huge 24(3x^2+20x+12).\) Did you understand that?

    Now, you would substitute 5 in for x, getting your final volume.
