Final answer:
The resulting cross section of a cube after one corner is sliced off will have a minimum of three square sides.
Step-by-step explanation:
The resulting cross section of a cube after one corner is sliced off will have a minimum of three square sides.
When a corner is sliced off, it creates a new face with three edges and three vertices. These new faces are square in shape and are called cross sections. To find the minimum number of square sides, we count the number of new faces created, which is three.
Therefore, the resulting cross section will have a minimum of three square sides.
