Cylinders and prisms have the same formula for the volume, namely:
Volume = base area * height
So this settles (i) or (ii)
The area of a square is L², and that of a circle of diameter is πD²/4 = 0.785D².
So if the square's side length is equal to the diameter of the base, then the area of the square is bigger than the circle. This should settle choices (iii) and (iv).
If you have doubts about your choice, post what you think for a check.
