Mathematics
1 answer:
baherus [9]4 years ago
6 0

Answer:

  B) 3x^3 + 24x^2

Step-by-step explanation:

The volume of a pyramid is 1/3 the product of the base area and the height. The base is square, so its area is the square of the side dimension.

  V = (1/3)(3x)^2(x+8) = 3x^2(x +8)

  V = 3x^3 +24x . . . . . matches B
