Question

The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. Which kind of plane could it be? A. a vertical plane cutting two adjacent edges of the base
B. a vertical plane cutting two opposite edges of the base
C. a slanting plane cutting two adjacent edges of the base
D. a slanting plane containing exactly one edge of the cube

Answer 1

I think the answer is C. a slanting plane cutting two adjacent edges of the base. I thought of the Pentagon building in Washington where it also has a pentagon-shaped cross section. 

Answer 2

Answer:

C. a slanting plane cutting two adjacent edges of the base

Step-by-step explanation:

The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. The plane could be - a slanting plane cutting two adjacent edges of the base.
