Answer:

x³ + 10x² + 31x + 30

Step-by-step explanation:

Volume = (x +5)*(x + 2) * (x + 3)

            = (x + 5) * [ x*(x+3) + 2*(x +3]

            = (x + 5) * [x*x + x*3 + 2*x + 2*3]

            = (x +5) *[x² +3x + 2x + 6]      {Combine like terms}

            = (x +5) (x² + 5x + 6)

            = x *(x² + 5x + 6) + 5*(x² + 5x + 6)

            = x*x² + x*5x + x*6 + 5*x² +5*5x + 5 *6

           = x³ + 5x² + 6x + 5x² + 25x + 30

           = x³ + 5x² + 5x² + 6x + 25x + 30

           = x³ + 10x² + 31x + 30
