Answer 1

D aka (x³+2x²)/3 cm³

Explanation:

Answer 2

(x³+2x²)/3 cm³

Explanation:

Find the diagram attached

Volume of a pyramid = 1/3 * Base area * height

Base area = x*x

Base area = x²

Height = x+ 2

Get the volume:

Volume of the pyramid = 1/3 * x² * x+2

Volume of the pyramid = x²(x+2)/3

Volume of the pyramid = (x³+2x²)/3 cm³
