Question

The oblique prism below has an isosceles right triangle base.

Answer 1

Answer:

A.

Step-by-step explanation:

In the figure attached, the oblique prism is shown.

The volume of the prism is:

V = b*h

where h is the height and b is the area of the base

Given that the base is an isosceles right triangle, its area is:

b = 1/2*x²

The height of the prism is (x + 2). Then, the volume is:

V = 1/2*x²*(x + 2)

V = 1/2*x³ + x²
