Answer 1

Answer:

2x^3 + 6x^2

Step-by-step explanation:

Volumen = area * height

You already had the area which is:

x^2 + 3x

and the heigth is 2x

Volumen = (x^2 + 3x)* 2x

Volumen = 2x^3 + 6x^2

Answer 2

Answer:

○ 2x³ + 6x²

Step-by-step explanation:

You multiply the height of 2x by x² + 3x.
