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
