Answer:
The resulting cross-section will have a minimum of three sides.
i.e. a triangle will be formed.
Step-by-step explanation:
Because on cutting a cube along the corner we will obtain a triangle and thus a triangle has three sides.
Hence, the resulting cross section will have minimum of three sides.
( Also we can obtain many other figures on slicing a cube in different ways.
If we slice a cube parallel to the base we will obtain a square.
when we will slice the cube to it's diagonal we will obtain a rectangle.
and in many other ways)
